I have an old Koto sword. It's a gimei Suinshi Masahide, so it probably was originally an unsigned blade of average to low-quality. It's also pretty "tired" and there are spots where the welds opened due to over-polishing. As an art object, it is completely worthless, but made an excellent serviceable weapon for iaido. In my young, stupid days, I tried to cut through a box I had that had paperbacks in it. I heard a large "ting" sound when I cut into it. I had forgotten that there was a metal Christmas tree stand in the bottom of the box. Fortunately, the sword only had a very mild, slightly rolled/chipped edge. The Christmas tree stand had a cut of about an inch deep in it.

Your sword is durable Asano -san, it's seems that you broke it because you hit it right at the most vulnerable spot, not to mention, your sword is very flexible. I can tell that this is a big sacrifice for you, but i believe that, through this harsh test, you can level up 👍 Amazing work Asano -san 👍

Tremendous respect to you the smith who spent hours upon hours to forge this shinsakuto and use it on a destructive test! Thank you so much to do it in the same scientific way recorded in period accounts as well! This instantly debunked tons of nonsensical rumors and myths about nihonto and swords in general. Swords are consumables. Properly made swords are very durable to endure all the offensive and defensive tasks but each blow and parry diminishes the sword in some way. Good for you to use a proper blade without excessive niku and show that it does tameshigiri exceptionally well with proper edge geometry and sharpness before moving onto the abusive tests! Thank you for showing the cross section after each breakage! This is an obligatory watch for anyone interested in swords! I have no idea how this immense educational and entertaining video hasn't got 10 million views!

I believe heavy niku was present on many historical blades particularly ones meant for war. I don’t think there is such thing as a “proper blade” shape. Just blade shapes for different circumstances. The one here that seems to have no niku would have been serviceable for civilian self defense / duels but for one intended to bring into battle, more niku would be preferable.
@FortuneFavoursTheBold
@FortuneFavoursTheBold Жыл бұрын
Incorrect. The amount of niku is up to individual smith/school’s preference. There’s absolutely zero evidence to suggest more niku means the betterment of anything. Definitely worse performance at cutting, and not necessarily not better durability. Something doesn’t cut as clean has a better chance stuck in the target and twist therefore bending the differentially hardened blade. The edge durability primarily comes from the individual heat treatment, and has a lot less to do with the amount of niku.

@@FortuneFavoursTheBold I don’t know what kind of katana you have cut with, but they should not have niku so extreme that they aren’t able to fully cut through a target. That is taking it way too far. Blade shape is a trade off between durability and sharpness. They are inversely related. Idk where you came to the conclusion that niku would leave your sword with less sharpness *and* not help it’s durability. You’d have to wonder why sword schools even bothered with it if it were to only give downsides. Say you have edges of the same hardness. One edge is 25 degrees while the other is 45 degrees. Cutting through the same tough target will show you that the blade with the narrower angle will take more damage. The more stout blade would’ve taken less. *Blade shape definitely does matter* kzbin.info/www/bejne/iZLUc5pohb-frMWV This isn’t the best example but it works.

@@outsideiskrrtinsideihurt699 Where did I say having niku will make them not cut through a target?? Where? I said worse performance. Katana are not purposed in history to cut through straw mats. Swords were used to cut people. Limbs are generally less of a problem. Torsos as a common target is an entirely different story. Not to mention torsos are protected by clothing and textile protections. Cutting through something cleanly, or failing that being able to drag out as a slash one-motion to the cut will reduce the chance of the blade getting stuck in a target and getting twisted and bent, which are the primary way to damage katanas, as the spines are soft from differential hardening. Having larger edge angles from having increased niku WILL increase the drag and resistance the blade meets, that is simple physics. There is no way around it. It also increase the chance of the blade getting stuck in a target. Japanese swords already have cutting portions (near the point of percussion) thicker than swords from other cultures, and having tons of niku WILL definitively increase the chance of it getting stuck. That's just a fact. It's not something you can talk out of. Having some niku might theoretically increase the resistance of it taking a set, but in practice, it actually worsen the performance and actually increases the chance it gets damaged in some ways. It's also not a trade-off between durability and "sharpness". "Sharpness" describes how fine the apexing of the edge is. What you meant to say is the "edge geometry". You can have bad edge geometry but the edge apex can still be well sharpened. Those are completely separate concepts to begin with. Having worse edge geometry will worsen both the performance, and in practice the durability. Unless the way you use the sword is smacking it sideway onto a log instead of cutting into appropriate medium. Now having niku AKA convex geometries on the edge bevel isn't too much worsening, but it worsens it nonetheless. If you go back to the kotō period of swordmaking, where swords were actually used instead of being put onto a rack in a residence to "ward off evil spirits", they tend to have less niku, and swords with minimal niku were more common, and swords with more distal tapering were more common. Because performance actually mattered at the time. The more recent shin-shinto katana are more of decorations than weapons of war. Smiths were clearly less experienced hence less confident to actually make blades with proper edge geometries, or making blades of proper length.

@@outsideiskrrtinsideihurt699 And I've said it, and I will gladly reiterate: kudos to Taro Asano to have the confidence and skills to not only make blades of proper edge geometries to maximize the performance, but also use said blade for destructive testing.👍 Not like some makers who deliberate present a cheat-sword made specifically for durability tests with chunky cross sections and less distal taper so they might appear good in destructive testing while in reality performance like a crowbar. He actually shows you the blade works well in tameshigiri, and then show you the cross section of the breakage.

I trained in Iaido for a few months but worked with a machete for several years in habitat restoration. I cut hard and soft woods and hard and soft vines. My take away after more than 10,000 strokes was...more important than how hard I swing is speed and angle. I felt most tested by the harder yet flexible vines. When swung badly my blade might turn in my hand and sometimes go flying through the air like a spring. I've also cut through my target and hit my own leg. When cutting well through vine, my blade would ring like a bell which told me it was a clean cut. I cut Tatami once in Iaido. I was new and at the end of the line. In my opinion, all the practitioners were way too self conscience. Too much thinking. I admit I wanted to shine but when it was time there was only the target. I walked up to it...and sliced through it with conviction. I was happy and looked up to see that my Sensei had missed it. I unlike everyone else had "failed" to hesitate. I think the mind being tense in anticipation causes the body to tense up which slows the body down and keeps the blade from reaching proper operating speed. If the mind at the very moment of cutting is fully there and not anticipating nor hesitating, then everything is enhanced.

This clearly disproves the notion that katana could bend easily and goes to show how a blade that the smith has little confidence in can still perform excellently in an extremely brutal test. May I ask, because you didn’t have much confidence in the blade from the start, would you say it was medium quality, low quality, or somewhere in between? Thanks!

A sword that bends from an edge strike would have to be VERY poorly made by modern standards. Even against steel. When people who know anything about swords say that traditional katanas bend easy, they mean from lateral force. To do that on a tatami mat would require messing up on a level that even new cutters won't do after a 5 min session on how to cut. The test where they put lateral force on the sword with the wooden stick bent the sword in ONE HIT on the strong of the blade. That kinda does show that traditional katanas do in fact bend easily. And break easily when hit on the spine...as that broke the sword in once again one hit.

@@ColdNapalm42 ​ I don’t think you understand what kind of wooden sword they used. Sure it’s wood, but that is a suburito meant for strength conditioning. They are supremely hefty and are essentially clubs (almost like kanabo). That paired with the fact that the base the katana was resting on (the tatami and cinderblocks) had zero give so the katana had to take the entirety of that force. Even then the bend was not dramatic at all. This test was deemed brutal for a reason. How could you expect any sword not to bend from a strike to the side like that? And at what part did it bend from edge contact? Did I just miss that part?

If you're planning on a similar test in the future, how about making a Kamakura style blade with a somewhat high shinogi and thick shinogi-kasane, but enough taper and Fumbari, and a noticeable Ha-Niku? Maybe that would show different results. Oh, and question about this test sword. How thick was the Kasane? And I don't see the curves of Niku in the cross section.

I believe that you'd witness pretty similar results up until the flex test, though if anything, the European sword would likely take more edge damage due to being softer. A classic through hardened European sword would flex more easily, and would be significantly more resistant to taking a set. But I do believe that it would snap at the point that the katana cracked. They are both swords, in the end. Extreme testing like this is very informative, but does not truly represent the rigors of actual use, some of which will be less damaging; and, likewise, some will be more damaging. Though as a final note, an Albion sword will be made with modern 5160 high-carbon steel. The sword used in this test was likely made of traditional tamahagane. The idea that tamahagane was somehow "bad steel" by pre-modern standards is ridiculous, but it has significantly lower properties than modern alloy steel. For reference by the way, I am an instructor in Historical European Martial Arts, and a practitioner of classical kenjutsu. I own fine examples of both European and Japanese swords, and have spoken to people who have done similar tests in person.

A very well made sword can flex and return to true (but not even close to what an albion can do), but most would flex a bit and then bend and even the best would bend after a point. Slack hardening, uneven tempering, thin blades and iron cores meant that there was a high risk of bending with european swords. Many in museums are very very bent.

Amazing! Well done for being bold enough to test your own swords in the pursuit of perfection. I think your hamon was too narrow - the hard steel had nowhere else to go but backwards into the soft steel, where it twisted. I look forward to seeing your next sword 🙇‍♂️

It's generally accepted that narrow hamon are less liable to be damaged than wider more flamboyant hamon which make a large amount of the body of the blade too brittle and liable to break.
