I'm going to be real with you...I don't have my original script or any of my notes/resources/books/papers for this episode since I made it 5 years ago. I lost a lot of my scripts and work-in-progress writings the beginning of 2016 and this video was one of them. Very sorry I couldn't provide sources so you could explore more. I will, however, leave you with a link to the book I mentioned "Stuff Matters" because it is fantastic!

[@ivankyleasiado7079]

Omg. Even here?? Do you live in youtube or something?

[@MegaFarinato]

A couple of things: Katanas arent anything special, they had a really hard time making them back in the day becouse that "volcanic steel" was of very low quality and had many impurities, althogh you could make an argument about the curvature and stiffness of the sword making cutting "easyer". Which brings me to the second point, the cuts performed here were a bit awkward, very little slicing and too much pushing the blade through the "stuff". Check some good HEMA cutting competitions or just some good cutting tests, youll see people cutting tatamis without the thing moving an inch And living bone is much easyer to cut than dry dead bone. Living bone is moist and bendy so you can slice through it with greater ease.

[@charlescourtwright2229]

Wonder if a Scottish claymore would be better

[@TheOnlyToblin]

I was going to comment the same thing. Those weren't the greatest cuts. The edge alignment wasn't great. Don't get me wrong, this shit's hard, but calling them a "master" seems like a stretch.

[@Questionmark142]

@@charlescourtwright2229 depends in what claymore you mean, since the word itself simply means "great sword" and was applied to different swords throughout history. I have a guess which one you mean, namely the late medieval two handed Scottish longsword, but another frequent use of the word was for the 17th and 18th century Scottish basket-hilted sword or broadsword (which is btw. the only sword to properly call a broadsword). I gotta admit, this is pretty nerdy, but using simple names for swords is most of the time very imprecise and too generalized.

[@Questionmark142]

About cutting performance of Katanas. The curvature of the Katana is to minor to really have an effect. The stiffness is not so important for cutting and more important for thrusting. What is important however is a sharp edge and to maintain a sharp edge you need a hard edge which is something the Katana is known for. It isn't sharper than other swords per se, but it is easier to keep very sharp and will stay so for longer.

[@IISocratesII]

Yep, i was about to comment on this myself, Katanas are decent cutters but the blade lacks mass at the percussion point, which hinders it when cutting through wide targets (as opposed to something like a Falchion or Lange Messer), and the most noticeable thing is that blade is not sharp, his edge alingment isn't perfect every time but there should be no issue with those cuts yet they look terrible, that's a dull blade, the tatami is clinging on.

The steel used in this video, (the ancient one that I’m not even going to try spelling), isn’t particularly good steel. It’s effectively just bloomers steel in a larger furnace. It has a lot of impurities, and a very imprecise carbon content. Europeans in the same time period had much better steel. Please go watch Shadiversity’s video on katana misconceptions (or his video on Japanese vs. European sword misconceptions.)

[@65firered]

Additional detail, the steel was folded many times into thousands of layers to remove impurities in the steel, this does not increase the quality of the steel.

I don't know if they established it very well, but I think the point was the ability to cut with a more average sized sword, the same as Geralt does in the example. A question of using technique to get more out of the tool, not a question the tool itself. The whole video feels a little rushed, so it's hard to tell.

[@LordVictorHalgaard]

@@nessesaryschoolthing Even then: Geralt uses longswords or hand-and-a-half swords, which are longer and have slimmer sections than Katana, meaning more leverage, and less resistance, due to a sharper angled grind. And yes - there was probably a reason it wasn't released initially, though I appreciate that they did!

[@Eralen00]

@@LordVictorHalgaard Yes but Katanas usually are thicker blades and have more mass, and therefore more momentum to cut through more easily. The curvature of a katana also facilitates slicing.

[@crestofhonor2349]

Dobert different swords were good at different tasks. Some swords were meant for stabbing rather than cutting. Edge alignment is also extremely important because if you don’t align the edge parallel to the direction you are cutting it could cause the blade to bounce off or cut poorly. Any material can also be cut to be as sharp as you want so keeping a blade a sharp a possible will be very important when it comes to cutting. In order for a blade to cut it must have enough exert enough force over a small area. So having a sharp blade makes it easier to make a cut in the material

[@CharlesLaCour]

First of all there is more to sword cutting ability that how fine the edge is, you also need to worry about blade geometry. If you have a very fine edge but a steep angle the blade will be a poor cutter. The thinner the better up to a point where the edge becomes weak. Also modern steels are much better materiel for blades than any steel used in historical blades, Japanese swords included. Tamahagane is actually a fairly poor type of steel for making a blade, a big part of the reason for the folding process is to purify the steel. A katana probably not the best style of cutting a body in half, a wider heavier sword would be ideal. On the TV Show Time Warp they have James Williams who runs Dojo of the Four Winds cut through a large pork shoulder and the sword went through the meat and bone with no problem, yes a human torso is larger but with a better cutting sword I have a feeling that it is doable.

[@braydenscott8058]

Tamahagane was an ideal metal used for that style of forging as it had a lot of carbon but in essence yes there are better-forging methods and steels today, then there were 500 years ago its just the method of tempering that created the legend of the katana and how good of a sword it was.
