I would settle for a finished sharpened un-hilted blade that I could make a custom hilt for... I wish more manufacturers would offer bare blades. hint...hint Honestly, no bare blade for sure due to policy in mainland china. Plus no complex hilt unless we recovered from the expense of Supreme Cutter and the next project.

I just did. Very impressive cuts. I wonder how much of it was the sword and how much the skill of the swordsman? percentage wise? Do you think you could have pulled this challenges off with a super sharp Albion Principe for example?

I succeeded with that cut with some other top notch sword but only on smaller target. Thigh is a record breaking one. You just have to think, can Principe takes PPR core without suffering damage? :) It's not just sharpness in the play here. It's Lancelot-Sharp, sharp enough to cut kevlar, but strong enough to survive cutting living bone hardness.

However, I can't guarantee there would be no damage taken.

This is a compare, using typical lung chuan edge on forearm target. One can see how the cutting stand and the target was knocked around and requiring powerful strike to cut the thinnest target.

Western butcher knives aren't that much harder than western swords, 56ishHRC, else steeling wouldn't work any longer. That's why in japan steeling a knife isn't really a thing since they like them harder. Harder knife means longer edge retention but also more likely to chip than roll. The steels are different as well, sword steel is more likely to be more tweaked towards toughness and knifes are more likely to have harder steel and temper. About the angle: Not 100% accurate, any angle can have a very acute apex, you can get an 60°inclusive (30°/side) angle shaving sharp like you can a 34°inclusive, but since there is more of a wedge, it will feel duller when cutting something because of drag. There is an article about impact resistance and edge geometry somewhere as well as one about edge stability. Unfortunately these tests are all about "normal" push cutting, as you rightly said, the forces involved in a sword hit are much different. As far as I have read, nobody has really done a test with chopping instead of push cutting. Interesting to hear about the people and sharpness, in my experience, most that are into swords or knives are knowledgable about sharpness as well, though there are many that don't really go deep into the rabbit hole. Most casual users though just do not care. I know people who never sharpen knives and don't even care that they need to saw at the chicken filet for minutes to cut it... And city people are much more likely to know nothing about sharpness (or blades in general). If you need your knife to be sharp for your livelihood you might not know the science but you will know how to sharpen a blade, though there are always people who would rather somebody else sharpen it for them.

That was a good video. I’ve watched and gritted my teeth on some handlings of swords, in reference to maintaining the edge. If you don’t mind, I’d like to add something FWIW concerning western swords and this goes about as much for their sheaths. I frequently draw and return with gravity holding both vertically. This is more important the older the sheath is. Not all antiques have a wood core. With the blade in the sheath, it’s acting to support preventing the sheath from bending. If drawn horizontally the sheath has no support and is subject to bending without a blade, not good for the sheath especially for the older, dried out ones, resulting in cracking. Cracking is possible but less likely on the newer ones, but nevertheless. With the unit vertically and gravity doing its job there is less pressure on the edge resulting in a longer life for both. This works out well for double edged jobbies. For practicing a fast draw with a katana, substitute an iaito. It’s safer and there is no need to worry about the edge.

How old would you say the sheath can get until it begins to become brittle? If nobody cares for it, it's probably a quite short time, also probably depends on if the air is dry or wet.
There are some things you can do to lengthen its life like leather conditioners (for furniture or saddles, I think some modern makers recommend cleaning the leather at least once a year with something like this), but since sheaths are pretty thck, I have no idea if it would work to resoften it. Also at some point there is just no way to any longer.

You are asking for finite answers where infinite ones exist. You might as well ask how long is a piece of string. You are right, there are leather conditioners, the trick is to get people to use them.

Part 2 of the "Optimized fighting sword" test, adding 8 swords as the contestants. It shows how good Longship Armoury swords are, for Little Cutie is as fast as LK Han Jian, while the Han Jian couldn't cut the same targets at all. Divider, a powerful sword at Nodachi length, is as fast as an aluminum Iaito. However, Supreme Cutter Classic is faster than any of them.

Hello again.
Where do you prefer to have discussions concerning the swords you have been developing for sale, and the testing and comparison you are putting these new swords against? Please let me know if my questions are not clearly stated.
