And you shall have one, if you contact this maker and ask for a sword made to this exact specifications. I believe they still have all the measurement requirements give by my buddy who designed it.
Nice! Fingers crossed that RVA will make this piece a production model. It's close to my "grail" katana, which would be a wide, yet thin hira zukuri style blade, but with distal taper and some niku. This way it could be light and fast, but still a devastating cutter. I can dream! ;-)
Wow amazing katana ! Congratulations on such a wonderful purchase! I was very impressed by the blade, its width, geometry, everything about it is perfect! I really like the Yamato design!
Thanks for posting the video and for all your hard work. That is a thick sword blade! I once saw a sword that is said to have belonged to Nobunaga Oda, and although it was not as long, the blade was thick and powerful. It would be great if the balance with the grip blades is good!👍
Thanks for the comment, and glad that I can provide some entertainment with my videos. This design is now being turned into a regular model to be produced but per my recommendation will be made with mono-tempered Japanese super-steel, instead of the differentially hardened steel to be more durable, and has the tsuka increased by 3-5 cm in length, along with the nakago inside, to provide better counter-balance and more leverage for the user.
Awesome overview Kane. This is a wicked sword, and you did a great job covering all of the intricacies of how it operates. It certainly cuts a mean profile in addition to being a fearsome cutter. Also a great PSA about the shampoo bottles: everyone should be aware of exactly how durable some types of plastic can be, and when we do our backyard targets, they can certainly cause risk to more thin/brittle edges. Great cutting and great contextual overview!
Thank you so much! Indeed, I regret to a certain degree of using it on inappropriate test cutting medium. I examined the shampoo bottle dispenser later and found the plastic to be very thick (much more so than plastic piping, as there's only tiny space in the middle for the shampoo to go through, but the whole chunk of plastic is THICC). Good news is that the sword still cut it through like butter, but for sure differentially hardened blade with such a small edge angle isn't the kind of sword you want to use on that.
Seen a bunch of japanese cutter use blades like that. Cant wait to get my hands on one. I voted for hira zukuri from John. That would cut smoother than a shinogi zukuri.
Indeed. John asked me about the preferred cross section and I voted for this setup with shinogi-zukuri either the spine tapered back in thickness from the shinogi-ji, as it reduces some weight but still keep the edge angle from being too small. Still at the cutting portion it’s at 10 degrees, which is quite crazy. Being made in hira zukuri will make the edge angle even smaller. A risky gamble for sure.
I have a custom kanmuri-otoshi zukuri odachi blade mounted with 16th century European hilt furniture that has a similar blade width to the sword in this video. It was a proof of concept piece, and is right at the limit of what a functional sword can be. I just need to get some Berserker Armor now. Edit: I also have a custom shobu zukuri katana with a blade proportion similar to a niuweidao, and that blade swells to a little over 2 inches near the optimal cutting section. Both of these swords are great cutters.
@@FortuneFavoursTheBold The odachi/greatsword's motohaba is 5.08 cm / 2 inches, it's nagasa is 106.68 cm / 42 inches, and has an overall length of 152.4 cm / 60 inches. It's big enough to make my Albion Archduke look dainty in comparison. The smaller sword has a motohaba of 5.08 cm / 2 inches at its widest point, a nagasa of 73.66 cm / 29 inches, and an overall length of 104.14 cm / 41 inches. I was mistaken previously, this sword has more of a hira zukuri blade, and the combination of the katana style hilt along with it's relatively deep sori make this sword look very interesting IMO (and better than my photoshopped mock-up indicated).
@@zenhydra Nice. I have a couple of nodachi and miao dao in that size range, but the base widths aren't that wide. I would like them to be wide enough and then tapers more in the profile to make them more maneuverable.
@FortuneFavoursTheBold I spent some time trying to calculate the non-linear, but very significant, distal taper the blade would need to make it wieldable, but actually capable of surviving cutting a charging horse's legs out from under it (it's original purpose). Once completed, I deemed it capable of being able to actually go up against the concept of mythical monsters. Even at my six and a half foot stature (and broadly built), its mass pushes my ligaments and tendons to a limit that I'm not sure is reasonably surpassable. I can muscle my Archduke into moving like a longsword, but trying that with this monster sword would end up with a visit to an orthopedist for me. It forces me to use circuitous montante/zweihander techniques to prevent injury.
Its looks like you have a great collection of swords. I also have many piles of swords in corners still, I did get an additional larger horizontal sword rack made to fit more of my collection though. You should also check out the French briquet swords. Many have one very Long single bevel and they are some amazing cutters. I have two antique examples and they are some of my best cutting swords.
Yes, I do have a French infantry briquet from the late 18th century, it has a short saber blade either custom made, or shortened from a decommissioned saber. It's a very lively sword that's not even that short, with a 27.8" blade. I even compared it to a Wakefield Hanger in this short video. th-cam.com/users/shortsxyNeCI9WkMU
One video I would like to see you tackle is a history and comparison of the various types of sugata and koshirae through out the transitional periods, like a typology breakdown. It's particularly hard to find info on early Tachi as allot of what's available is in Japanese and outdated websites. Granted, I know you're already bricked up between the last 2 videos and all the reviews you have to put out lol.
@@FortuneFavoursTheBold nice to hear, I'm actually trying to run a Tachi design by ShadowDancer, loosely based on a Kamakura sword called Akashi Kuniyuki. Probably won't happen this year, but it's on my high priority list when once I get my 2 other projects started.
Btw, if you look up that sword, good luck, there's an anime character with the same name so the search results are absolutely fucked lol. I had to dig around on Seskos site for like 3 hours to get some real details on it lol.
This is the detailed sword page about Akashi Kuniyuki www.touken-world.jp/search-noted-sword/kokuho-meito/54135/ 13th century Japanese swords have far more interesting geometries than the most common reproductions of Edo period run of the mill katana. These tachi have non-linear curvature on the blade-more curved at The tang and the lower 1/3 of the blade than the upper 2/3 of the blade. It’s just something modern makers rare care to replicate. Akashi Kuniyuki also has a relatively slender blade with more distal taper, which is seen on earlier tachi often-because they have longer blades and are meant for war rather than the wall. There is also the double bo-hi (the upper one is shorter) and the reinforced kissaki, and the engraving on the base of tje blade. There are just tons of details here and I’m not sure Shadow Dancer is the one to go for, even though they make good swords in general. They are not known for making historical replicas and stepping outside their comfort zone. I think Cloudhammer is a worthy contender for the project given how willing they are to take on custom projects with interesting features.
@@FortuneFavoursTheBold nice find. Also yeah the way the horimono acts as a double Hi and transitions to a larger single Hi is pretty amazing and part of what made fall in love with the sword. And your right about the sori being really complex, I can't tell if it's Koshi or Tori, it kinda has traits of both. For reference heres are the basic specs I drew up a few days ago from the info i could find. Nagasa: 32.5 inch Sori 30mm Motohaba 34mm Sakihaba 20mm Motokasane 8mm Horimono/Double Hi: 8 inch Kissaki 1 inch I know it's a little big but tried to keep the proportions the same. Kinda like if a Nanbo or Shinshinto era smith saw the blade and wanted to remake if lol
Lol wow, left your videos on autoplay while I was doing some chores. Walked back in around 16:40 and was floored by the dimensions of this thing on my 70 inch tv lol. Definitely think this would benefit from having a longer tsuka, probably 12 inches with a katatemate or hiramaki for smoother grip. I do wonder if this would benefit from nagamaki style fullers, with a short stout bohi and a thin sohi going up the length of the shinogi to balance it, so its easier to maneuver without taking away from the momentum needed to cut through thick harder targets.
It definitely would benefit from a longer tsuka, maybe 13"-15". An ubokubi-zukuri geometry would benefit the handling as well, but it might loose some heft for being such a chopper!
Wow that thing is cool. 3lb 5oz seems a bit heavy tho I guess it's due to the specialized nature. Would be cool to have one that's toned down and maybe thinner. Cool concept and well presented video, man!
@@KF1 Indeed! And Brother Nathaniel is working with them to fine tune the details of the sword, and switching to koshirae that can appeal to everybody.
Yes, as I explained, this is a custom design by a buddy of mine. It’s almost twice as broad as a typical katana, but it’s not thicker, it’s thinner. You can’t have something that’s both thicker and wider, it would be unusable.
The kissaki is actually very long, about 7mm from the tip to the yokote. It’s only because the blade is so broad that the length of the kissaki isn’t immediately obvious.
@@FortuneFavoursTheBold Understood. I'm speaking very broadly/generally of course, but for the period mentioned O-kissaki would be even more exaggerated in proportion to width.
@@Lord_Marquaad Generally yes because they were often shorter overall with shorter handles too. They were usually attached to a belt on a sling by their side with a Korean bow or spear as the primary weapon.
Yes, I do know that. Korean swords have wider blade with a triangular wedge as cross section, which is usually referred to as hira-zukuri on Japanese swords.
Hira zukuri blades tend to be lighter than shinogi-ji blade provided everything else including the width, thickness are the same. But Korean swords tend to have wider blades, so they are not necessarily lighter than Japanese swords of the same size.
I'm imagining this in a blade length akin to the longer Odachi (45" nagasa?) but with a very deep fuller and more European esque width and distile taper (10mm motokasane, 4mm sakikasane) to try and get the weight down to manageable levels.... How much do you think i would have to beg Ryansword to make that happen? Lol
Shouldn’t be too hard for them. But would cost more than usual for sure. Still I think it should be manageable within $800. BTW it’s some excellent stats for an odachi, some 14-15th century antiques actually have similar degree of distal taper. 10mm is a very good starting thickness.
@@FortuneFavoursTheBold i'm glad you approve of my choice of dimensions, i'm too used to getting incredulous reactions when i mention wanting to have a "beefier" katana in my collection... this would be far larger than "beefy" but hey, i'm also a monster hunter fan.
haha. that katana is a multipurpose sword just change the handle too wenge or hinoki Wa handle and you have a nice Maguro kiri bocho not only good for cutting tatami mats good for slicing large portions of large fish. from a competition cutter to fine sushi sashimi omakase. jokes aside that wide nagasa looks like a Maguro kiri bocho and the bevel are zero grind like most gyuto and yanagiba. the angle of the bevel too is 10 degrees most kitchen knives are 17 degrees and some Japanese kitchen knives are 12 degrees and I sharpen mine 14 degrees on both sides for better edge retention than 12 or 10 its sharper than most kitchen knives.
You can contact Ryansword on their website (link in the description of this video), or via Facebook, and ask them to make an exact replica of this same sword. I believe they still have the stats. You can also ask for some modifications such as a slightly longer tsuka--which I recommend.
@FortuneFavoursTheBold Thank you! Yes, I will probably request a 12 inch tsukq. I've seen those wide katanas in Japanese tameshigiri kids but I didn't know what these were called nor where to purchase one.
Well an osoraku zukuri will start the transition to the tip far earlier in the blade thus making the blade at the point of percussion narrower, which kind of defeats the purpose of this design of having very broad blade throughout for maximized cutting potential.
I want one.
And you shall have one, if you contact this maker and ask for a sword made to this exact specifications. I believe they still have all the measurement requirements give by my buddy who designed it.
