It makes me imagine that much of the sword's ability to cut has to do with the fineness of the polishing, which reduces the 'drag' as it cuts through 'an object'; somewhere, i read that, in early days, the katana was tested by cutting through a convicted criminal. It was said that a criminal, who knew this fate, would try to swallow small stones, in order to damage the sword used to execute him....strange stories, but brutal times...
since these guys did chemical analysis of the katana steel I'm surprised there's no mention of silicon or manganese content, as nearly all modern industrial steel contains those two elements in addition to iron and carbon.
in video after video I hear that a katana is durable because it has a hard outer shell and a tough inner core, but that just doesn't make any sense, for the inner tough core to bend at all the outer shell has to also bend, which means the outer shell will crack, about all you can really say is that a crack in the outer shell will most likely only propagate to the core and the crack will stop there, the sword is still in one piece but it is definitely damaged. Also in every video I've seen the outer shell has about 3 times as much material as the inner core, so again there's so little core that I don't see how that can make a difference.
Yeah the whole bit about the different hardnesses giving it more durability doesn’t make sense to me either. Katana are durable due to their thickness from what I know
Second time I've watched this and I will most likely watch it again , great content and the skills shown are getting very rare which makes me feel privileged , thanks for sharing .
No one can match wootz steel talwar nd shamsir... bt world lost that wootz making process.. no steel is better then south indian wootz steel for sword...
6:23 .... may as well've used a baseball bat. I saw nothing special there. Better katanas show an instant perfect cut rather than "pushing" the object off to one side.....
Anyone who has experience in sharpening - ACTUAL FREE-HAND SHARPENING, not RaZuR sHaRp EZ kits - knows that it's anything but boring. I personally shave with a knife I sharpened myself, but it took a culmination of literal years to get to the point I am now after 20 years. Some things people may not realize by watching: - as you sharpen, you begin to feel the correct angle and even the grit seems like it's talking to you and relaying information between what the blade is telling you. You start talking to it like so, "am I pressing hard enough? Too hard? Is this angle right? I need to relax my shoulders more. Did I just feel a burr? What technique am I going to use next? Was that return stroke right? Let me do that one again."
Steel with elastic properties and high yield strength. Usually it has to be an alloy that can be cold worked to final shape or heat treated to give it ideal properties. Typically spring steel is a general term to describe characteristics of a steel that can return very close to it's prior shape after a force has been excreted on it. A resistance to deformation.
