17:06 This is probably why swords from the gladius to the migration era "Viking" sword didn't have much of a guard. If you didn't block with your shield the sword was likely to bend or break.

15:31 Car crash physics. The most force would be when both swords are swung with power and both impact. Essentially you get the force and leverage from both fighters concentrated in one spot.

I really appreciate your efforts! Just a quick off-topic question: My OKX wallet holds some USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). How should I go about transferring them to Binance?

I think I might be testing this method on a few antiques soon! Very interesting, as always.

Truly a top notch location

I gots to get me one a dos 🤘💀 I like what you did with the pommel!

Nice carving! The result speaks for itself.

I used the same method. 1. Antique British 1796 light cavalry sabre: 10.6kg, and 11.3kg if I force the flex to occur on the other side (so there's a preferential side for the flex, the curvature also is an issue for this one). 2. Albion Brescia Spadona: 18.5kg (makes sense since this is a triangular blade with a stiff anti-armour type blade) 3. Albion Machiavelli: 9.4kg (feels stiff) 4. LK Chen Ribaldo: 7.6kg (it has about 7cm more length on the Machiavelli for the same type of blade; less stiff, but it feels good and as I expect such a longer side-sword to feel) 5. Windlass Christus Imperat Rapier: 5kg (this feels floppy like a noodle; and flex is not everything, its spring nature feels bad; hard to describe) 6. For my HEMA trainer, one-handed side-swords are almost always 9kg (3 different makers; basically same flex), and a longsword feders is 13kg (seen as a bit on the threshold of being too stiff in the community that prefers more 11kg). I also have a semi-custom Black Fencer rapier with a 114cm blade, which flexes at 9kg, seen maybe as too stiff for a rapier trainer that usually has only about a 7kg flex. As a last thought, I like a bit of a flex in cut-focused side-sword blades, they feel more authentic for the 1500s, but probably that's more to do with the correct weight distribution on the blade as the good quality steel of the period allowed for quite thin blades. At the same time, a bit of flex in thrust-focused blades feels bad; I need to feel that I push through before I feel the blade bending. And no, I didn't expect the Machiavelli to have the same flex as a trainer since they do feel different as blades go; so flex is definitely not the entire picture.

13:26 "One of these sabers is not like the others, of these swords is just not the same." 🤣 Cold Steel out here making the 1796 Light Calvary Katana.

Hate to correct you, but heat treatment has virtually no impact on the elastic modulus (ie, "stiffness") of carbon steels, nor most (possibly even all) tool or stainless steels. For all intents and purposes, a sword's stiffness is determined solely by its geometry, with minor contributions from the choice of alloy, though the moduli of almost all steels used in swords are within 5% of each other. This is a common misconception that likely stems from heat treatments' effect on the yield point (ie, how much the metal can be deformed before it can no longer spring back into its original shape). Metals tend to behave like they aren't as rigid when they're permanently deforming, and the more a steel is hardened, the higher its yield point and the more force is required to put it into that "bendy" state.

Of course there's steel typing for modern replicas. 1045 carbon steel's generally the lowest to go. 1040 much of the time makes a sword blade too soft. 1095 results in hard hitting swords and a blade that's not too much less flexible. Though they're more vulnerable to breaking due to increased brittleness. Stainless steel for the purposes of a sword is too resilient to bending and thus alot more likely to fracture. No surprise spring steel; otherwise known as 5160 steel, is excellent for this, but is notably more expensive. There are currently a couple of Asian sword designs that are made with T10; which falls between 1095 and spring steel. Though T10 hasn't been perfected yet. As for the sword-like objects epee and foil, the modern designs being extremely flexible is highly beneficial.

Now thats a knife

The best way I have found is to put the blade into a standard flex rig with degree markings & then use a hanging scale attached to the pommel to see how many lbs are required to flex the blade to the same degree mark. However how much flex one wants can indeed vary quite a lot from sword to sword, user to user, task to task.

Finding the least amount of force needed to flex a blade is interesting, but I’m really interested in the minimum force needed to bring a blade to critical failure, be it bending or breaking. Though, you’d probably go through many swords to find that out.

I think its a shame you have neglected to property review your Peserey Shamshir! I got one about the time you released your pumpkin cutting short... nobody's talking about this guy. Why? Wait, maybe I should become a swordtuber...?

Really fun video! Its interesting to see how much edge geometry and cross section effects thrusting.

👍

I just purchased one myself and I feel like it’s much more flexible than the one I see in your video. When you’re pointing the sword at the camera, it doesn’t look like it droops downward much while the one I have significantly drooped when held horizontally. Also, the one I have wiggles around a lot when you shake it in the direction of the flat, definitely whippy just wondering if the one you have is like like that as well.

9:50 I’m not sure that I agree with this assessment. The only (truly!) famous Japanese warrior/Daimyo to have (occasionally) wielded a sword without tsuba is Uesugi Kenshin; and most illustrations of Kenshin show him with typical tachi/katana - i.e. with tsuba. This was of course in the latter part of the Sengoku Jidai / last part of the Muromachi period.

8:45 - that bow could simply be a longbow instead of a Yumi. Longbows of a selfbow variety (eg. made from a single piece of wood) were pretty common in Southern China because they were easy to make and easy to maintain in southern China's warm and humid subtropical climate. Since most of the pirates by this time were Chinese, then they would've come from the southern coastal regions and would be familiar with longbows.

I wonder if the absence of guards was more common on ships due to how much easier storage would be. I mean, storing swords with disk-guards is annoying at the best of times, but when you have to store a bunch of them together in very limited storage space that is constantly rocking, rolling, and bouncing? Sounds like a giant PITA, at best.

Good to see the quality of the print and framing! I think the flared swords on the chinese boat may be connected to the Song dynasty podao / shoudao, but difficult to say for sure!

That's really cool! 🤘💀 and it does make me wonder if they were dual wielding? Probably, I would say... probably. But who knows

I know there was one account written in one of the books in Saturnino Monteiro's Batalhas e Combates da Marinha Portuguesa series, of a montante versus several swordsmen. But I can't seem to find it atm, sorry.

Not bad. Framing in itself can be expensive to have done. Art is quite a hard thing to judge though. It's all about where society is at the time on how popular something will be.

I am the wild life of Florida LOL

I feel the dual wielding swords is a product of the Chinese artist or that individual is experienced in Chinese style swordsmanship. While Japanese swordsmanship does have dual wielding, it is with a longer and shorter sword. From what I’ve seen, there aren’t any Ryu that use 2 of the same length blade whereas that can be seen in Korea and China. In addition, we see that in China across several centuries and with various blade types. From the small butterfly swords to even 19th century European-style sabers.

Very good big chap😊

"Aduarte" is a very peculiar name. If it's anything like portuguese Dom Eduarte, it comes from english "Edward", which is very odd for a Zaragoza middle tier nobleman.

Thank you for providing the recording and data of this experiment. I've always been curious about this. 😂

Great video!

ho damn! that thing cuts fantastic 🤘💀 beautiful sword!

I like that you are very aware of the rigour level when it comes to the scientific method... below MythBusters (I love that you took a jab at them, that show was not that scientific even when they were trying; still fun to watch though 😅). But for real, once you stated that and talked a bit about the aspects that can affect the results, it made me enjoy the artistry of the test even more. 😇

Very cool video! I think these comparisons are really useful, thank you!
