When making this shield, I said please note for when they use it (and maybe state this to the audience who will ask), the plate isn’t designed to be bullet proof or any such nonsense, it’s purely for the guys to test what happens to even a thin, lightweight composite of Kevlar. Carbon fibre would add stiffness, but is far less ideal in an armour application. It’s just to see how little material can stand up to how much force. A Kevlar laminate with an internal material such as ceramic, metal or another item is the ideal, but this is just to see what some UV damaged Kevlar can sustain.
I was thinking something similar. Imagine a breastplate in steel but with an external cover of kevlar. That could make the steel part thinner getting the same level of protection if not straight better!
Do you think it would gain significant defensive properties if it was doubled in thickness? Or is it less useful than just having the internal hard component?
fibre orientation is key as well, kevlar strands are ncredibly strong but not stiff so they will be parted by piercing impacts. 8 layers of say 0/45/90/135 etc fibre orientation may provide better protection against piercing. A thin ply of high carbon cold formed steel in the impact face would make this ridiculously good.
material science is kinda designed for this sort of thing. Like Jamie said though Ill paraphrase the difference between science and screwing around is recording things.
I need to remind myself that this man of unbridled energy and charisma has chronic fatigue, its just incredible how Shad performs when he has a good day.
I know all about how he feels on his bad days and after they are done filming as I suffer from the same. I am sure those filming days totally suck all his energy out and mostly likely he will suffer for days after it.
For those that are interested, Kevlar is made out of hundreds of layers of weaved nylon-style twine. Each individual layer of this weave isn't very secure by itself since a spike can find its way in between the weave, but multiple layers of it will absorb a lot of the pressure through a stab. This is why you can see some kind of fraying with the axe cuts as the cuts tear the nylon-style weaves apart only in the outer-most layers of the Kevlar as the inner layers absorb the impact. I imagine the resin that keeps it all together also helps with the ductility of the material, making it more resistant to cuts.
The weakness with Kevlar vests and similar is that you VERY easily shoot through them with a modern fixed hunting broadhead. Both with bows and crossbows. I have been shooting and hunting with bows since 1986 and I have done some testing for the police as a friend I have is in a special unit and it totally scared the crap out of them. Even with rather light bows and crossbows, you can shoot totally through a pig carcass having a bullet proof Kevlar vest on as long as you avoid heavy bones. Through both the front and the back of the vest with the pig in between. That made the special police unit being very worried about criminals having crossbows. Now they use similar armor carriers and grade 4 armor plates as the military use because of those risks.
@@The_Judge300Not surprised. The shield in this video and kevlar vests by themselves are defeated by the same principle. Extreme force in a very small area.
I think rather than using the kevlar as a standalone shield, you could instead layer it over the front of a regular shield and make it considerably stronger. This could also allow you to make the regular shield much thinner and end up with less weight, but make it much more resistant to blows.
I would have layered it at the back, but as I said to the guys when I sent them the piece, Please note for when they use it (and maybe state this to the audience who will ask), the plate isn’t designed to be bullet proof or any such nonsense, it’s purely for the guys to test what happens to even a thin, lightweight composite of Kevlar.

@@jamesmckenzie9551 I'm not a fan of ceramic. You can have plastic plate armor up to level 4 and it can still take bludgeoning without shattering. Most of my enemies use baseball bats, skateboards, hammers, axes, and other such weapons because they believe owning a gun is immoral. Of course they would still try to kill me with one of said items for having a different opinion while claiming the violence is justified. People give steel a pretty shitty reputation because it is heavier and does srawling or whatever they call it while only going up to level 3, but people forget it takes a bullet made with multi layering to piece a steel plate. And that's just against mono layer. And if I could afford ceramic plates to go into a plate carrier up to level 4 then why wouldn't I just use that kind of money to build a forge so I can just make steel plate that is better than military grade?
The key to modern armor is layered composites. You take that stuff and layer it with steel and carbon fiber, and I bet it'll stop dang near everything. Especially if you get it in a proper curved shape. Also, the British dragon scale armor is a modern composite scale-mail that can take a point-blank granade.
I’ve worked with Kevlar, it’s definitely not the miracle material people sometimes think it is. As a shield I would have made it 1/2” thick, or made a kevlar sandwich with other materials. Still entertaining and educational to see what a thin sheet like that can handle though.
When you only have wood & steel, it's as magical as the guy with the steel sword vs the guy with the bronze one. When you are ignorant of a thing & it's limits, it's easy think of a thing as magical.
@TheSilverShadow17 It's good in it's niches. I'm a fan of them myself...even if I have to admit it needs to be longer to complete better against a lot of EU style designs.
@@xxxlonewolf49 I like the Katana myself too, but not to the extreme like a weeb who'd simply gatekeep the sword and proclaim it as being invincible/magical, etc. It has it's pros and cons and the design showcases specific attributes more than others. The O-Katana might be a temporary fix on the blade length issue but if there's any kind of analogue that fixes the primary issues with Katanas, it's more likely the Kriegsmesser imo.
You didn't test sword to the edge! I was waiting for it. With that lightness, you could have extra protection behind it round the arm. Imagine a full size Kite shield in Kevlar, or the roman shield!
This does raise an interesting point. What about the metal-layered shields? The bronze covered Greek hoplons are a famous example, but were there examples of heater shields covered in thin sheets of steel or some such? How well would they perform?
Bronze covered and a couple inch thick solid oak. Then the 8 ft spears overhand in the other hand. Those guys must have had shoulders the size of basket balls.
I think my favorite thing about you three is watching you guys be good enough friends to cajole and yell with each other and stay friends the whole time. Keep up the wonderful content my dudes!

@@mrkiky well you see here when a guy of only 5 ish years of experience wants to do this and is in a rush he isn't able to rember the names off everything correctly so that tiny axe with a spike on the end reminded me of a tonahawk and so i put that, If you know the correct answer please i would recommend in future leaving it in your initial comment to save us both time
How do y'all keep coming up with these ideas? I'm over here thanking the heavens that I just get to pull from a very ancient collection of Japanese stories and not have to actually come up with much, but you guys are over here practically ushering in a neo Renaissance with all these creative projects. My hat's off you gentlemen.
All fiber armor (Kevlar, Carbon fiber, etc) have similar characteristics. When made thin, they are more flexible, and more resistant to blunt force but weak against piercing. But when ply and resin reach certain thickness (depend on the material), they will lose flexibility and become very rigid. Then they are more resistant against piercing, but weak against blunt force.
I love the chemistry I feel sometimes testing of things is just very plain and if we’re watching TH-cam we want to just enjoy the experience and I feel this newer content is really shining in the sense of having fun we have to remember this is a fun hobby we all love and we should have fun with it! Thank y’all for making some fun and enjoyable content
He did hit a head shot! That's great! Like shad in the other video! I have to say I think the competitive nature and friend vibe it's a lot of fun I enjoy the dynamic!!
Now, you make a Heater shield like Nate’s , but the cloth covering is formed of the Kevlar and Resin. Make the wood backing about half as thin, and you’ve got a composite material shield with a lot of advantages .
I've been wondering about this match up for years, glad it's finally getting played out on this channel! The Kevlar shield would be like witchcraft back then, they would think it's enchanted.
i like how much emphasis you put on the fact that many shields, norse viking age shields especially, were used to trap blades. its a very over looked function. if you havent already, i suggest looking into hurstwic/william r short. his viking age combat analysis is second to none. i think you guys will find the videos of the combat moves from the sagas tested very interesting! his book Men of Terror is also the best book ive read on viking age combat tactics
09:30 no cracks and no Delamination... yes wow - incredible construction and the Beak resistance. Good armour, very good. Now get james to make full 3D carass profile in 1mm Titanium - put that kevlar under it & send @DemolitionRanch
10:25 And this result is why I was stunned at why you guys used a drill to make the holes in it rather than use a sharp needle-thingy that widens gradually, clammed into/mounted on something such that you can use force/pressure to punch the holes for the string. Mention of the resin had me reconsider that approach but again this part shows that smooth, pointy stuff is Kevlar's bane as it does not allow the fibres to catch on and entangle to ensure force bleed-off. 21:19 A wild STICK appears! 😮
I like to imagine that Nate is there as the audience stand in. Shad and Tyranth constantly antagonize each other while Nate just watches the chaos along with us
Todd Cutler made an oldschool composite shield using glue, iron filings, and crushed glass inside a leather and wood construction, and it ate a shocking amount of punishment despite the weight increase.
From my admittedly minor knowledge that'd perform worse an be more time intensive to produce. Somethin bou how it works to stop things by spreadin ou impact forces over it's entire surface area an how it's made in sheets an then cut to size. So ya wanna use as few pieces o as large a size as ya can for each project. I think. All o what I've said cou be wrong.
@@valteine each scale would be a small circular shield it self. Think a miniature Captain America shield.Overlapping each other. With a backing shield to hold them in place made of Kevlar. So even if something does piece through it’s likely not to penetrate all the way through.
@@jamesmckenzie9551 the Kevlar is about half the weight of a normal shield so even double it’d be a normal weight. The scales would still be strong and even if they break it’s not catastrophic to the whole. Plus with the idea of a shield being used to bind up the opposing weapon it’d be more likely to do so. As for helping sure, sounds fun.
I clicked notifications to go to your last Knights Watch video and I walk into this. YT didn't even show a notification badge that something new showed up.
Tyrent you came in the wrong time period mate!! God damn, with this spike spear thing you tried after the arrows, you are terrifing more than Arthur Dayne holding dawn or egon the conquerer holding blackfyre itself, great work everyone ❤
Of note, everything that penetrated the kevlar shield did get stuck to some degree. At least enough to allow someone momentary control of the weapon. Take the kevlar style shield, scale up the size for better cover and double the layers; you'd have an impressive shield. The doubled thickness would still be lighter than a traditional shield, it would do much better at absorbing impact force and the outer layer would be great at essentially trapping weapons.
Gotta say, that was pretty impressive. And it does occur to me that if the lack of weight ever became a problem with that kevlar shield, you could always laminate it onto wood in place of the leather/linen cover.
in regards to the thinness / transfering force issue mentioned near the end, you could use a bit of weight and just make a bracer/spacer sort of thing of wood that goes along the arm where the strap is. you could also sheet it in real thin metal too. and i'd wager you'd still keep it under weight for an equivalent size shield.
Next step is customizing - crimped metal on shield edge, and patterns on the shield face made with steel rivets (or metal washers stuck on with Flex Seal.
Always a good laugh to see you guys banter each other as the 3 of you are so competitive :) such a great chemistry, I hope one day Kramer will be back and stay with you guys :)
I don't wear watches anymore because I break them too often and I don't want to waste more money but I will say that the sponsors that Shad does take are vetted and approved by him and to the other side the ones he doesn't take on. I got scammed by a knife one that Shad refused to let sponsor him and I wish he woulda made that video 3 months earlier. So thank you Shad for having integrity
Two important points being missed here! 1. This technology is layer-able with the same or different weaves of Kevlar or wood (sense epoxy resin will bond to saturate wood incredibly effectively). I’d love to see a test against a shield using the same thickness or weight as the wood shield with pure Kevlar and or a combination of wood and Kevlar or a shield made from just wood and epoxy resin. 2. This material is extremely repairable. I say extremely because the repair points on my epoxy/Kevlar surfboard seem to be stronger (to me anyway) because of overlapping the fabric then it was originally. So you could have a shield, that if properly repaired might gain nominally in bulk but also more in strength the more it is damaged and repaired.
Quite correct, if they sent it back to me, I could repair the original piece, it would take about 4 hours for the big hole, and I’d add a capping layer over the entire piece.
I ride a surfboard made with Kevlar and and resin wrapped around styrene foam “Surftech” is the brand. Going off of that compared to fiberglass and carbon-fiber (5 to 10 x stronger then either) I’m predicting before watching this video that the armor will do exceedingly well.
With how light the Kevlar is, instead of comparing the wooden shield to the Kevlar shield, I’d say combine them! You get the rigidity of the wooden shield with added absorption of the Kevlar.
Yall should do a series where yall combine the information from all these tests to design the "ideal" armor. Look at things like what makes the best shield and what makes the best armor. You have pretty much been covering the individual materials so far but then go into hybrids of combining the materials where you theory craft layers of materials and which is the best combo. Think about things like a metal layer, fiberglass layer, carbon fiber layer, etc.. Also dont forget a padding layer underneath everything!!
A fascinating insight as always--I'd never considered shields as disposable items meant to capture and control weapons for short periods of time, and now the ancient Egyptian shields which were only wood and leather make much more sense. I particularly love that we paused this very analytical and focused investigation to admire a cool stick that Shad found, lol.
thank you so much for making a kevlar video I was dying to see this * haven't watched yet * just the idea of what kevlar would mean to the medieval age
The historical shield represents centuries of optimizing materials and design for that purpose. The kevlar shield is a modern material but it's just a random guess at what works with that material. Many years of iterative testing and development to find the best performer would likely yield markedly better results. It takes a fair bit of R&D to optimize composites for purpose.
I like the stuff you folks do! It's always a pleasure to see you folks test things out. Thank you! Allow me a question about Boromir. Is he supposed to have water or sand as a weight in the bottom part of his stand? I've been wondering about that for years now.
Boromir is a Century BOB or similar product. They are supposed to be weighed down with water or sand, to prevent tipping over, however they can be knocked over with enough force. Having practiced martial arts in the past, a well placed, full force punch can knock one over, so its not surprising that Boromir falls over to certain weapon strikes.
Thank you for the explanation. That alone helped me understand training dummies a bit more, but I must say that i'm sorry. I probably should've phrased my question a bit differently. What I wanted to know is, if Boromir has such a weighting in the videos, because to me, it doesn't seem like it. At least, to my untrained eye, I couldn't see any hints for a filled base. Because I don't really encounter such training dummies in my life, I always thought that they wouldn't fall back as much as Team Shad manages to make them fall back. Therefore i thought, Boromir would have a empty/semi-empty base. Yes, I understand that even with a weighted base, Boromir should still fall back sometimes, but i wondered about Boromirs current weight.
@@Junk_Knight I'd guess its partially filled. The training dummy can weigh upwards of 275 pounds when full with water or sand. However concrete can also be used. Seeing that no material is ever coming out the top of the fill hole, no matter how hard the dummy is hit/when it falls over, I'd guess its partially filled with concrete. The reason why this would be advantageous for Team Shad is that it allows the dummy to move back more than a full one while not falling over to the lighter blows to the head. This would I think be better for their weapons.
Great video, you guys! Glad to see Shad's feeling better. I do want to pose a question here for you guys. So, I'm in agreement that the shield that you guys tested was fairly comparable to Nate's heater shield. But the biggest concern that you guys laid out at the end was the absorption of the impacts on the shields surface. Would it be possible to alleviate that risk with more layers building up the shield? If it truly is that lightweight because of the material, adding a few more layers would not affect weight that much, plus with the additional layers and the proper curvature built into the shield to get weapons to glance off at the right angles, I feel like you could really alleviate the worry about the impact, while upkeeping the great level of light weight that you would have to carry around!
You made the point at the end but I was waiting to see just how it would compare actually in use. Sure it has the defensive stats of a comparable shield, or better, but with just how light it is and how the force doesn't seem to be dispelled too much would using it risk injury more? I mean if that took an axe to the top or outer edge of the shield would it flex or rotate enough to put pressure on or even damage the user?
Yep, I also wanted to see more slicing strikes, not only piercings. When you fight against someone with shield - the last thing you want to do is to try to pierce the shield...
I have a PASGT vest from 1990 that was never issued and that's made of 13 layers of kevlar. That's not enough to recommend it for bullets of any kind. It was designed specifically for catching shrapnel from high explosives, like grenades and shells, bit you had to be a minimum distance away. Yes, the PASGT vest, in certain instances, could stop small caliber pistol rounds, but only very, very, bery rarely. Do not go out, buy these old things, and expect it to stop bullets. You won't like the results. Rifle rounds will whizz right through without slowing down. Forget it. The kevlar they have is probably rated for bullets but I'm not an expert and can't tell. Thank you for the video Shad! I had thought about this bery subject years ago when I bought the PASGT vest. Edit: Personal Armor System Ground Troops, or PASGT. Apologies.
In another comment, the person they are working with stated that the shield is made of 9 layers of UV degraded Kevlar, though he didn't state which type, just that he used 4 layers of 4x4 twill, 1 layer of basket weave, and another 4 layers of 4x4 twill. For puncture resistance, unidirectional Kevlar is superior to woven Kevlar, all other factors being equal. Corrections officers often wear vests out of UD Kevlar for its stab resistance. The PASGT was I think the first U.S. military vest to use Kevlar, and used K-29. While able to resist the common pistol rounds of the day, including 9mm, it is vulnerable to follow-up shots and fails to higher tier threats. DuPont has replaced K-29 with KM2 and KM2+ for military applications.
@@kungfugirevik657 Yeah, not something you'd want to get shot in. They did have an add-on armor package of ballistic plates, but you had to wear it over the PASGT vest and it's ridiculously bulky and heavy, not worth it. As a matter of fact, and I know this is way of subject, but the Gundam creators came up with the Zaku Stutzer which has a stylized add-on armor scheme that's based on it. It looks ridiculous.
@@kungfugirevik657 Yeah, that extra armor is an odd add-on, but that's what that early plate carrier looked like. I don't have one, but I'm sure there's surplus out there. The best itself looks like something the Imperial Guard would wear.
I would combine the eras and put that Kevlar shield against a shield of the same dimensions, made from hardwood. The edging material could be used to secure the laminations together, as well as a glue. I would be interested to see how that same shield would do with a backing. With a wooden backing, could there also be a liquid resin/kevlar-fiber filler-product that could be dolloped into the holes?
US Military Kevlar Blast and Bullet proof shields are approx. 2 to 3 inches thick sometimes with plexiglass (thick) window at top to use while shooting around edges. They are made with many layers of kevlar.
It’s understandable that this is not bulletproof. However, the concept is pretty great. I could see this maybe two or three times thicker as a Talwar (a medium shield that is strapped to the forearm) Ended doing a really great job of stopping most smaller projectiles like nine mil and 45 arrows, spires, swords and axes maybe even the spike! I would love to have one made like that❤
honestly? Lately i fight some depresion and other deamons and seeing you joking and poking each other reminded me times when i used to have social life. Thanks for that and also for all the other content (btw: english is not my language so i apologize for mistakes and hopefuly its still "decodable")
A decade ago Brother Shad was a fan of katanas, a decade later he preferred the good old fashioned European sword. Another caveat, is that medieval times built everything for wartime whereas we built things for adventure in modern times but now we build things for a more eco conscious society.
Keep in mind, military combat helmets are made of kevlar and resin. Those are rated to stop up to a 9x19mm round, and will. Though you'll probably have one heck of a headache, I don't know. Fortunately, I never took one to the helmet. And quite honestly, I'd like to keep it that way. I'm not 100 percent positive, but newer helmets may be made of Aramid fiber these days, which is stronger than Kevlar and rated for longer life, I think.. I don't know for certain.
The one problem with kevlar is not knife proof, that is why most law enforcement around where i live where plates now more than soft armor. But amazing video as always guys.
Now make the Kevlar shield as thick and same size and see how that performs. Also I worked in a place that made stab proof vests on the side, layer in some rough sandpaper while you are at it, tends to really slow a blade down and dull it at the same time. Like I in my youth, I wasn't able to like proper downwards shank through I think it was 6 layers of sandpaper, tho I was using a cheap worksman's utility knife. But as is the way in the eternal arms vs. armour race, on armour side layering is the key where each layer brings a beneficial property to the table and in the flipside you add layers to the projectile or blade, shape, mass and speed, shape for what you intent to destroy then mass from blade thickness and the speed from strenght and lenght, results may vary and the most succesful ones go down in history and be remembered till the end of time!
Been thinking about this idea before to make a shield out of modern materials but I always imagined using epoxied, laminated fiberglass with a thin layer of hard metal on the outside and kevlar inserts for the inside. The outer metal material would deform tips or glance blows, the fiberglass layer provides structural stability and can capture splinters and fragments and the last kevlar layer catches the projectile, much like modern wearable armor design really.
so i cant say much because of an nda, but i work with ballistic shields, the kind used in riots by police, and also raids where criminaals are using guns, but we make shields with similar size to that , that being said we dont use kevlar but other materials. they arent too thickk but can be a little weighty, but we use a waterjet in order to cut out the holes for being assembled.
Military helmets are often made of kevlar and are shaped and held together by using a resin much like this, so it should not compromise the protection of the kevlar
For use as a shield, put it with a backing of wood. Not as thick as the other shield, but enough to disperse some of the impact- and catch the minor penetrations like arrows.
Ah yes, 3 famous types of lads. -The Yapper -The "Thinks he's Superman" -Dad I myself am of the Yapper archetype, so I will now proceed to yap. Prefaced with the "I have no idea what I'm talking about here, BUT..." I feel like I'd be really interested in seeing what sort of combos between armor types result in the best protection for the least weight. Alternatively I wonder if you could create some sort of reliable numeric scale for how good armor is overall based on weight and defensive capability. Like, get the weight of 1 square meter of each type of armor, put it through testing (ideally with some sort of machine that is dealing out the slashes and stabs so you know what amount of force, in newtons, is being applied), then make a graph or spreadsheet of each type of armor and how much it weighs vs how many newtons of force it could withstand via slashing and stabbing. Then you could start layering armors and seeing if the effects are additive or multiplicative. Of course, you'd also need to have a way to adjust the results with noted weak points in various armor types. I guess you could make a gradient over the graph with letter grades for total armor rating, and have a + or - system for strengths and weaknesses that aren't quantified by the initial testing. For example, if the graph's x-axis was weight (lightest to heaviest from left to right), and the y-axis was the amount of newtons of force it could withstand (from lowest to highest, bottom to top), then you could make a sort of gradient from the top left to the bottom right (adjusted to fit any emerging patterns that might show up in the data, I'd presume? Not a statistician) of grades from A to F. You could then take the grades of each armor and adjust them based on any practical weaknesses or strengths they have, where each pro is a + and each con is a - that moves the letter grade up or down. By directly quantifying the numbers in test results you can also generally see what percentage of effectiveness experimental/modern armors have compared to medieval staples.
When making this shield, I said please note for when they use it (and maybe state this to the audience who will ask), the plate isn’t designed to be bullet proof or any such nonsense, it’s purely for the guys to test what happens to even a thin, lightweight composite of Kevlar.
Carbon fibre would add stiffness, but is far less ideal in an armour application. It’s just to see how little material can stand up to how much force. A Kevlar laminate with an internal material such as ceramic, metal or another item is the ideal, but this is just to see what some UV damaged Kevlar can sustain.
Interesting. Thanks for helping Shad, Nate and Tyranth. 🫡
I was thinking something similar. Imagine a breastplate in steel but with an external cover of kevlar. That could make the steel part thinner getting the same level of protection if not straight better!
Do you think it would gain significant defensive properties if it was doubled in thickness? Or is it less useful than just having the internal hard component?
fibre orientation is key as well, kevlar strands are ncredibly strong but not stiff so they will be parted by piercing impacts. 8 layers of say 0/45/90/135 etc fibre orientation may provide better protection against piercing. A thin ply of high carbon cold formed steel in the impact face would make this ridiculously good.
material science is kinda designed for this sort of thing. Like Jamie said though Ill paraphrase the difference between science and screwing around is recording things.

For those that are interested, Kevlar is made out of hundreds of layers of weaved nylon-style twine. Each individual layer of this weave isn't very secure by itself since a spike can find its way in between the weave, but multiple layers of it will absorb a lot of the pressure through a stab. This is why you can see some kind of fraying with the axe cuts as the cuts tear the nylon-style weaves apart only in the outer-most layers of the Kevlar as the inner layers absorb the impact. I imagine the resin that keeps it all together also helps with the ductility of the material, making it more resistant to cuts.
The weakness with Kevlar vests and similar is that you VERY easily shoot through them with a modern fixed hunting broadhead.
Both with bows and crossbows.
I have been shooting and hunting with bows since 1986 and I have done some testing for the police as a friend I have is in a special unit and it totally scared the crap out of them.
Even with rather light bows and crossbows, you can shoot totally through a pig carcass having a bullet proof Kevlar vest on as long as you avoid heavy bones.
Through both the front and the back of the vest with the pig in between.
That made the special police unit being very worried about criminals having crossbows.
Now they use similar armor carriers and grade 4 armor plates as the military use because of those risks.
@@The_Judge300Not surprised. The shield in this video and kevlar vests by themselves are defeated by the same principle. Extreme force in a very small area.
@@RhapsodicXStyle07you know that seems to be a common occurrence for the most common weapons throughout history? I think I’m onto something…
I think rather than using the kevlar as a standalone shield, you could instead layer it over the front of a regular shield and make it considerably stronger. This could also allow you to make the regular shield much thinner and end up with less weight, but make it much more resistant to blows.
A layer at the back wou prolly be handy as well
Maybe sandwich the layers of shield with kevelar between like they use to do with wool.
Thats what I was thinking, I’d be surprised if they didn’t come to the conclusion to but didn’t add it to the video for some reason.
I would have layered it at the back, but as I said to the guys when I sent them the piece,
Please note for when they use it (and maybe state this to the audience who will ask), the plate isn’t designed to be bullet proof or any such nonsense, it’s purely for the guys to test what happens to even a thin, lightweight composite of Kevlar. Carbon fibre would add stiffness, but is far less ideal in an armour application. It’s just to see how little material can stand up to how much force. A Kevlar laminate with an internal material such as ceramic, metal or another item is the ideal, but this is just to see what some UV damaged Kevlar can sustain.
@@jamesmckenzie9551 I'm not a fan of ceramic. You can have plastic plate armor up to level 4 and it can still take bludgeoning without shattering. Most of my enemies use baseball bats, skateboards, hammers, axes, and other such weapons because they believe owning a gun is immoral. Of course they would still try to kill me with one of said items for having a different opinion while claiming the violence is justified.
People give steel a pretty shitty reputation because it is heavier and does srawling or whatever they call it while only going up to level 3, but people forget it takes a bullet made with multi layering to piece a steel plate. And that's just against mono layer.
And if I could afford ceramic plates to go into a plate carrier up to level 4 then why wouldn't I just use that kind of money to build a forge so I can just make steel plate that is better than military grade?
@16:35 is the perfect frame to describe this channel. I'm glad i've been able to see this channel grow and evolve. Continue to do your work Shad!!
10:00 (impressed whistle) Once again, Nate shows there's nothing he cannot destroy with a keen blade and a can-do attitude...
Heck yeah! Can't lie this is one of my "drop everything " go to's.
The key to modern armor is layered composites.
You take that stuff and layer it with steel and carbon fiber, and I bet it'll stop dang near everything. Especially if you get it in a proper curved shape.
Also, the British dragon scale armor is a modern composite scale-mail that can take a point-blank granade.
I’ve worked with Kevlar, it’s definitely not the miracle material people sometimes think it is. As a shield I would have made it 1/2” thick, or made a kevlar sandwich with other materials. Still entertaining and educational to see what a thin sheet like that can handle though.
When you only have wood & steel, it's as magical as the guy with the steel sword vs the guy with the bronze one.
When you are ignorant of a thing & it's limits, it's easy think of a thing as magical.
@@xxxlonewolf49One classic example is of course, the Katana.
@TheSilverShadow17 It's good in it's niches. I'm a fan of them myself...even if I have to admit it needs to be longer to complete better against a lot of EU style designs.
@@xxxlonewolf49 I like the Katana myself too, but not to the extreme like a weeb who'd simply gatekeep the sword and proclaim it as being invincible/magical, etc. It has it's pros and cons and the design showcases specific attributes more than others. The O-Katana might be a temporary fix on the blade length issue but if there's any kind of analogue that fixes the primary issues with Katanas, it's more likely the Kriegsmesser imo.
@TheSilverShadow17 Agreed on O-katna or Nodachi(sp?) And kriegsmesser of course...but handle looks painful
You didn't test sword to the edge! I was waiting for it. With that lightness, you could have extra protection behind it round the arm. Imagine a full size Kite shield in Kevlar, or the roman shield!
Yeah i was waiting for that
Roman shields are crap.
This does raise an interesting point. What about the metal-layered shields? The bronze covered Greek hoplons are a famous example, but were there examples of heater shields covered in thin sheets of steel or some such? How well would they perform?
An what if a kevlar layer or two were added to those, eh?
i think kevlar as the backer and 2m hardened steel in front. acting as a Face hardness@@valteine
Bronze covered and a couple inch thick solid oak. Then the 8 ft spears overhand in the other hand. Those guys must have had shoulders the size of basket balls.
I think my favorite thing about you three is watching you guys be good enough friends to cajole and yell with each other and stay friends the whole time. Keep up the wonderful content my dudes!
It's so nice and refreshing to see Shad behaving that energetic and in a good way childlike! Makes it such a cozy video!
P.S. Get Nate his own microphone already, plzzz.
7:27 weppons testing, works but the spike of tomahawk got through
13:00 Arrow testing, works
17:55 poleaxe, no Herbert, testing, worked but your weppon is stuck so the sheld works as it disabled your weppon
22:10 weight comparison to something roughly same size
In summary it works just as well and if it doesn't block the strike from sharp stikes (or possibly spear not tested) it will disable the weppon alowing you to strike, doing the job of a sheld
I don't see how that can qualify as a tomahawk though
@@mrkiky well you see here when a guy of only 5 ish years of experience wants to do this and is in a rush he isn't able to rember the names off everything correctly so that tiny axe with a spike on the end reminded me of a tonahawk and so i put that,
If you know the correct answer please i would recommend in future leaving it in your initial comment to save us both time
@@theromanorder It's a 14ish century battle axe. Considerably bigger than the average tomahawk.
I love how you guys get along together! It makes me smile, laugh, and warms my heart!
Shad! That was a fantastic stick. I'm impressed
I love the bickering between close friends.
I remember heated debates amongmy friends in my old D&D group about such mundane topics as "Could a light saber kill a Balrog?" Classic geekiness.
Best exercise.
21:20
That is a pretty nice stick. A little short, but overall quite pleasing to the eye and sensibilities.
It's no fun being jewish.
How do y'all keep coming up with these ideas? I'm over here thanking the heavens that I just get to pull from a very ancient collection of Japanese stories and not have to actually come up with much, but you guys are over here practically ushering in a neo Renaissance with all these creative projects. My hat's off you gentlemen.
And they're clearly having fun doing it.
All fiber armor (Kevlar, Carbon fiber, etc) have similar characteristics. When made thin, they are more flexible, and more resistant to blunt force but weak against piercing. But when ply and resin reach certain thickness (depend on the material), they will lose flexibility and become very rigid. Then they are more resistant against piercing, but weak against blunt force.
I love the chemistry I feel sometimes testing of things is just very plain and if we’re watching TH-cam we want to just enjoy the experience and I feel this newer content is really shining in the sense of having fun we have to remember this is a fun hobby we all love and we should have fun with it! Thank y’all for making some fun and enjoyable content
You can see why the knighted gentry of old was so competitive can't you?
He did hit a head shot! That's great! Like shad in the other video! I have to say I think the competitive nature and friend vibe it's a lot of fun I enjoy the dynamic!!
Okay... I love how wholesome those three are.
Now, you make a Heater shield like Nate’s , but the cloth covering is formed of the Kevlar and Resin. Make the wood backing about half as thin, and you’ve got a composite material shield with a lot of advantages .
I've been wondering about this match up for years, glad it's finally getting played out on this channel! The Kevlar shield would be like witchcraft back then, they would think it's enchanted.
i like how much emphasis you put on the fact that many shields, norse viking age shields especially, were used to trap blades. its a very over looked function. if you havent already, i suggest looking into hurstwic/william r short. his viking age combat analysis is second to none. i think you guys will find the videos of the combat moves from the sagas tested very interesting! his book Men of Terror is also the best book ive read on viking age combat tactics
I love the channel production lately. The new writing is great!
Protect this channel at all costs
09:30 no cracks and no Delamination... yes wow - incredible construction and the Beak resistance.
Good armour, very good. Now get james to make full 3D carass profile in 1mm Titanium - put that kevlar under it & send @DemolitionRanch
10:25 And this result is why I was stunned at why you guys used a drill to make the holes in it rather than use a sharp needle-thingy that widens gradually, clammed into/mounted on something such that you can use force/pressure to punch the holes for the string. Mention of the resin had me reconsider that approach but again this part shows that smooth, pointy stuff is Kevlar's bane as it does not allow the fibres to catch on and entangle to ensure force bleed-off.
21:19 A wild STICK appears! 😮
16:51 hmm... perhaps it's an opportunity for Tyranth to craft a new tip?
Just the tip.
@@DH-xw6jp yes.
I like to imagine that Nate is there as the audience stand in. Shad and Tyranth constantly antagonize each other while Nate just watches the chaos along with us
Todd Cutler made an oldschool composite shield using glue, iron filings, and crushed glass inside a leather and wood construction, and it ate a shocking amount of punishment despite the weight increase.
Make a shield that’s dragon scale pattern, each scale made from Kevlar
From my admittedly minor knowledge that'd perform worse an be more time intensive to produce.
Somethin bou how it works to stop things by spreadin ou impact forces over it's entire surface area an how it's made in sheets an then cut to size.
So ya wanna use as few pieces o as large a size as ya can for each project. I think. All o what I've said cou be wrong.
@@valteine each scale would be a small circular shield it self. Think a miniature Captain America shield.Overlapping each other. With a backing shield to hold them in place made of Kevlar. So even if something does piece through it’s likely not to penetrate all the way through.
Well, if I make them a dragon scale, will you come over and make it? Because it’s a ton of work for a worse, heavier product.
@@jamesmckenzie9551 the Kevlar is about half the weight of a normal shield so even double it’d be a normal weight. The scales would still be strong and even if they break it’s not catastrophic to the whole. Plus with the idea of a shield being used to bind up the opposing weapon it’d be more likely to do so. As for helping sure, sounds fun.
I clicked notifications to go to your last Knights Watch video and I walk into this. YT didn't even show a notification badge that something new showed up.
Tyrent you came in the wrong time period mate!! God damn, with this spike spear thing you tried after the arrows, you are terrifing more than Arthur Dayne holding dawn or egon the conquerer holding blackfyre itself, great work everyone ❤
Tyranth's patience is superhuman
Of note, everything that penetrated the kevlar shield did get stuck to some degree. At least enough to allow someone momentary control of the weapon.
Take the kevlar style shield, scale up the size for better cover and double the layers; you'd have an impressive shield. The doubled thickness would still be lighter than a traditional shield, it would do much better at absorbing impact force and the outer layer would be great at essentially trapping weapons.
Imagining a seasoned warrior do a whiny "Gimme my thing back!" while trying to yank their weapon out of a shield makes me smile out loud. xD
This was a fun one! Thanks guys!
Gotta say, that was pretty impressive. And it does occur to me that if the lack of weight ever became a problem with that kevlar shield, you could always laminate it onto wood in place of the leather/linen cover.
in regards to the thinness / transfering force issue mentioned near the end, you could use a bit of weight and just make a bracer/spacer sort of thing of wood that goes along the arm where the strap is. you could also sheet it in real thin metal too. and i'd wager you'd still keep it under weight for an equivalent size shield.
Next step is customizing - crimped metal on shield edge, and patterns on the shield face made with steel rivets (or metal washers stuck on with Flex Seal.
In humble regards to the plate armor comparison, would a kevlar shield that was curved deflect better or would the fibers catch?
Those watches look incredible, definitely gonna look into getting one
love they got the feeling of a knight(Shad) a veteran(Nathan) and a ruky(Tyrant)
That was an excellent stick, Shad.
The opening is top notch!
Always a good laugh to see you guys banter each other as the 3 of you are so competitive :) such a great chemistry, I hope one day Kramer will be back and stay with you guys :)
I don't wear watches anymore because I break them too often and I don't want to waste more money but I will say that the sponsors that Shad does take are vetted and approved by him and to the other side the ones he doesn't take on. I got scammed by a knife one that Shad refused to let sponsor him and I wish he woulda made that video 3 months earlier. So thank you Shad for having integrity
A car episode would be AMAZING. Keep being great guys. This was a blast.
Next time on Shadiversity: the Beq destroys an Abrams tank somehow.
Is it Beq or Beck?
It's actually "Bec"; it's French.@@kingzach74
wrap the kevler in a gambison material and retest. it will still be light and even better protection and padding
Two important points being missed here!
1. This technology is layer-able with the same or different weaves of Kevlar or wood (sense epoxy resin will bond to saturate wood incredibly effectively). I’d love to see a test against a shield using the same thickness or weight as the wood shield with pure Kevlar and or a combination of wood and Kevlar or a shield made from just wood and epoxy resin.
2. This material is extremely repairable. I say extremely because the repair points on my epoxy/Kevlar surfboard seem to be stronger (to me anyway) because of overlapping the fabric then it was originally. So you could have a shield, that if properly repaired might gain nominally in bulk but also more in strength the more it is damaged and repaired.
Quite correct, if they sent it back to me, I could repair the original piece, it would take about 4 hours for the big hole, and I’d add a capping layer over the entire piece.
I ride a surfboard made with Kevlar and and resin wrapped around styrene foam “Surftech” is the brand. Going off of that compared to fiberglass and carbon-fiber (5 to 10 x stronger then either) I’m predicting before watching this video that the armor will do exceedingly well.
"You can´t make a broken arrow worse" That belongs on a Shirt
With how light the Kevlar is, instead of comparing the wooden shield to the Kevlar shield, I’d say combine them! You get the rigidity of the wooden shield with added absorption of the Kevlar.
Kevlar sandwiched between metal sheets would be interesting to see. Ya know.. composites of hard and flexible layers to dissipate kinetic energy.
Yall should do a series where yall combine the information from all these tests to design the "ideal" armor. Look at things like what makes the best shield and what makes the best armor. You have pretty much been covering the individual materials so far but then go into hybrids of combining the materials where you theory craft layers of materials and which is the best combo. Think about things like a metal layer, fiberglass layer, carbon fiber layer, etc.. Also dont forget a padding layer underneath everything!!
In regards to armor using a lamalar or similar layer style can work rather well for carbon fibe &/or kevlar construction.
A fascinating insight as always--I'd never considered shields as disposable items meant to capture and control weapons for short periods of time, and now the ancient Egyptian shields which were only wood and leather make much more sense. I particularly love that we paused this very analytical and focused investigation to admire a cool stick that Shad found, lol.
thank you so much for making a kevlar video I was dying to see this * haven't watched yet * just the idea of what kevlar would mean to the medieval age
The historical shield represents centuries of optimizing materials and design for that purpose. The kevlar shield is a modern material but it's just a random guess at what works with that material. Many years of iterative testing and development to find the best performer would likely yield markedly better results. It takes a fair bit of R&D to optimize composites for purpose.
All this test was designed to do was to see what a thin amount of that material could handle, nothing more.
I like the stuff you folks do! It's always a pleasure to see you folks test things out. Thank you!
Allow me a question about Boromir. Is he supposed to have water or sand as a weight in the bottom part of his stand? I've been wondering about that for years now.
Boromir is a Century BOB or similar product.
They are supposed to be weighed down with water or sand, to prevent tipping over, however they can be knocked over with enough force.
Having practiced martial arts in the past, a well placed, full force punch can knock one over, so its not surprising that Boromir falls over to certain weapon strikes.
Thank you for the explanation. That alone helped me understand training dummies a bit more, but I must say that i'm sorry. I probably should've phrased my question a bit differently. What I wanted to know is, if Boromir has such a weighting in the videos, because to me, it doesn't seem like it. At least, to my untrained eye, I couldn't see any hints for a filled base.
Because I don't really encounter such training dummies in my life, I always thought that they wouldn't fall back as much as Team Shad manages to make them fall back. Therefore i thought, Boromir would have a empty/semi-empty base. Yes, I understand that even with a weighted base, Boromir should still fall back sometimes, but i wondered about Boromirs current weight.
@@Junk_Knight I'd guess its partially filled.
The training dummy can weigh upwards of 275 pounds when full with water or sand. However concrete can also be used.
Seeing that no material is ever coming out the top of the fill hole, no matter how hard the dummy is hit/when it falls over, I'd guess its partially filled with concrete.
The reason why this would be advantageous for Team Shad is that it allows the dummy to move back more than a full one while not falling over to the lighter blows to the head. This would I think be better for their weapons.
Thank you for your answer! That sounds reasonable and further helps me understand everything. You're the best :)
@@Junk_Knight You're welcome, glad I could help.
Huh...I never thought some shields were meant to be disposable. Thanks for the info.
damn. Gotta hit stuff with the hammer side more often the raw power of that thing is just awesome
Great video, you guys! Glad to see Shad's feeling better. I do want to pose a question here for you guys. So, I'm in agreement that the shield that you guys tested was fairly comparable to Nate's heater shield. But the biggest concern that you guys laid out at the end was the absorption of the impacts on the shields surface. Would it be possible to alleviate that risk with more layers building up the shield? If it truly is that lightweight because of the material, adding a few more layers would not affect weight that much, plus with the additional layers and the proper curvature built into the shield to get weapons to glance off at the right angles, I feel like you could really alleviate the worry about the impact, while upkeeping the great level of light weight that you would have to carry around!
You made the point at the end but I was waiting to see just how it would compare actually in use. Sure it has the defensive stats of a comparable shield, or better, but with just how light it is and how the force doesn't seem to be dispelled too much would using it risk injury more? I mean if that took an axe to the top or outer edge of the shield would it flex or rotate enough to put pressure on or even damage the user?
Yep, I also wanted to see more slicing strikes, not only piercings. When you fight against someone with shield - the last thing you want to do is to try to pierce the shield...
I have a PASGT vest from 1990 that was never issued and that's made of 13 layers of kevlar.
That's not enough to recommend it for bullets of any kind. It was designed specifically for catching shrapnel from high explosives, like grenades and shells, bit you had to be a minimum distance away.
Yes, the PASGT vest, in certain instances, could stop small caliber pistol rounds, but only very, very, bery rarely. Do not go out, buy these old things, and expect it to stop bullets. You won't like the results.
Rifle rounds will whizz right through without slowing down. Forget it.
The kevlar they have is probably rated for bullets but I'm not an expert and can't tell. Thank you for the video Shad! I had thought about this bery subject years ago when I bought the PASGT vest.
Edit: Personal Armor System Ground Troops, or PASGT. Apologies.
In another comment, the person they are working with stated that the shield is made of 9 layers of UV degraded Kevlar, though he didn't state which type, just that he used 4 layers of 4x4 twill, 1 layer of basket weave, and another 4 layers of 4x4 twill.
For puncture resistance, unidirectional Kevlar is superior to woven Kevlar, all other factors being equal. Corrections officers often wear vests out of UD Kevlar for its stab resistance.
The PASGT was I think the first U.S. military vest to use Kevlar, and used K-29. While able to resist the common pistol rounds of the day, including 9mm, it is vulnerable to follow-up shots and fails to higher tier threats.
DuPont has replaced K-29 with KM2 and KM2+ for military applications.
@@kungfugirevik657 Yeah, not something you'd want to get shot in. They did have an add-on armor package of ballistic plates, but you had to wear it over the PASGT vest and it's ridiculously bulky and heavy, not worth it.
As a matter of fact, and I know this is way of subject, but the Gundam creators came up with the Zaku Stutzer which has a stylized add-on armor scheme that's based on it. It looks ridiculous.
@@BeachTypeZaku I just looked up the Stutzer, and yeah, I can see it.
Definitely one of the more interesting looking variants.
@@kungfugirevik657 Yeah, that extra armor is an odd add-on, but that's what that early plate carrier looked like. I don't have one, but I'm sure there's surplus out there. The best itself looks like something the Imperial Guard would wear.
Now you should try a Kevlar shield as thick and heavy as the hita shield and see if it makes any difference!
I would combine the eras and put that Kevlar shield against a shield of the same dimensions, made from hardwood. The edging material could be used to secure the laminations together, as well as a glue.
I would be interested to see how that same shield would do with a backing.
With a wooden backing, could there also be a liquid resin/kevlar-fiber filler-product that could be dolloped into the holes?
US Military Kevlar Blast and Bullet proof shields are approx. 2 to 3 inches thick sometimes with plexiglass (thick) window at top to use while shooting around edges. They are made with many layers of kevlar.
It’s understandable that this is not bulletproof. However, the concept is pretty great. I could see this maybe two or three times thicker as a Talwar (a medium shield that is strapped to the forearm) Ended doing a really great job of stopping most smaller projectiles like nine mil and 45 arrows, spires, swords and axes maybe even the spike! I would love to have one made like that❤
kevlar over a thick yet light base of aluminum would be an interesting sci fi fantasy shield design
honestly? Lately i fight some depresion and other deamons and seeing you joking and poking each other reminded me times when i used to have social life. Thanks for that and also for all the other content (btw: english is not my language so i apologize for mistakes and hopefuly its still "decodable")
A decade ago Brother Shad was a fan of katanas, a decade later he preferred the good old fashioned European sword. Another caveat, is that medieval times built everything for wartime whereas we built things for adventure in modern times but now we build things for a more eco conscious society.
That was a pretty cool stick.
Keep in mind, military combat helmets are made of kevlar and resin. Those are rated to stop up to a 9x19mm round, and will. Though you'll probably have one heck of a headache, I don't know. Fortunately, I never took one to the helmet. And quite honestly, I'd like to keep it that way.
I'm not 100 percent positive, but newer helmets may be made of Aramid fiber these days, which is stronger than Kevlar and rated for longer life, I think.. I don't know for certain.
Kevlar is an aramid fibre, same family as nylon. Kevlar is just a brand name.
You are right, I apologize. I meant some of the modern aramid fibers you find available these days.@@jamesmckenzie9551
The one problem with kevlar is not knife proof, that is why most law enforcement around where i live where plates now more than soft armor. But amazing video as always guys.
Nate and Jazza are In League to Break Shad's Arrows
Now make the Kevlar shield as thick and same size and see how that performs. Also I worked in a place that made stab proof vests on the side, layer in some rough sandpaper while you are at it, tends to really slow a blade down and dull it at the same time.
Like I in my youth, I wasn't able to like proper downwards shank through I think it was 6 layers of sandpaper, tho I was using a cheap worksman's utility knife.
But as is the way in the eternal arms vs. armour race, on armour side layering is the key where each layer brings a beneficial property to the table and in the flipside you add layers to the projectile or blade, shape, mass and speed, shape for what you intent to destroy then mass from blade thickness and the speed from strenght and lenght, results may vary and the most succesful ones go down in history and be remembered till the end of time!
Been thinking about this idea before to make a shield out of modern materials but I always imagined using epoxied, laminated fiberglass with a thin layer of hard metal on the outside and kevlar inserts for the inside.
The outer metal material would deform tips or glance blows, the fiberglass layer provides structural stability and can capture splinters and fragments and the last kevlar layer catches the projectile, much like modern wearable armor design really.
It would make a great shield because they could add 3lbs of padding and still be lighter than Nate's heater whilst giving comfort from the impact
There are so many "that's what she said" moments in this video...
17:30 did they censor the word "squire" 😆
so i cant say much because of an nda, but i work with ballistic shields, the kind used in riots by police, and also raids where criminaals are using guns, but we make shields with similar size to that , that being said we dont use kevlar but other materials. they arent too thickk but can be a little weighty, but we use a waterjet in order to cut out the holes for being assembled.
23:00 what if you add a Kevlar layer, same thickness as the Kevlar shield, on top of Nate's regular shield? How well would that hybrid perform?
What if you made a thicker Kevlar shield so it was a similar either thickness or weight (whichever you get to first) as the traditional shield?
Military helmets are often made of kevlar and are shaped and held together by using a resin much like this, so it should not compromise the protection of the kevlar
Y'all are so entertaining and informative! I love the banter.
For use as a shield, put it with a backing of wood. Not as thick as the other shield, but enough to disperse some of the impact- and catch the minor penetrations like arrows.
Ah yes, 3 famous types of lads.
-The Yapper
-The "Thinks he's Superman"
-Dad
I myself am of the Yapper archetype, so I will now proceed to yap. Prefaced with the "I have no idea what I'm talking about here, BUT..." I feel like I'd be really interested in seeing what sort of combos between armor types result in the best protection for the least weight. Alternatively I wonder if you could create some sort of reliable numeric scale for how good armor is overall based on weight and defensive capability. Like, get the weight of 1 square meter of each type of armor, put it through testing (ideally with some sort of machine that is dealing out the slashes and stabs so you know what amount of force, in newtons, is being applied), then make a graph or spreadsheet of each type of armor and how much it weighs vs how many newtons of force it could withstand via slashing and stabbing. Then you could start layering armors and seeing if the effects are additive or multiplicative. Of course, you'd also need to have a way to adjust the results with noted weak points in various armor types. I guess you could make a gradient over the graph with letter grades for total armor rating, and have a + or - system for strengths and weaknesses that aren't quantified by the initial testing.
For example, if the graph's x-axis was weight (lightest to heaviest from left to right), and the y-axis was the amount of newtons of force it could withstand (from lowest to highest, bottom to top), then you could make a sort of gradient from the top left to the bottom right (adjusted to fit any emerging patterns that might show up in the data, I'd presume? Not a statistician) of grades from A to F. You could then take the grades of each armor and adjust them based on any practical weaknesses or strengths they have, where each pro is a + and each con is a - that moves the letter grade up or down. By directly quantifying the numbers in test results you can also generally see what percentage of effectiveness experimental/modern armors have compared to medieval staples.
ordered myself a watch, really good ad there guys
