My dad was a machinist he passed away before he could teach me to trade but I wish I could have learned he was the owner of J & M Tool Company in Dallas Texas he had an invention in the oilfield, a coupling that he designed and made. But I'm a welder nothing like a machinist but I do love metal work of any kind. A German showed me a little bit of metalwork like he did making fireplace kits this poker the tongs and everything by hand I did a little bit in the weld shop I worked in I love the metal work.

the process itself is a standard layered metal billet. so far the only variation is pulling a piece of the billet to make a tang. thats not to say it isnt difficult. i think it would more important to find out what type of metal he is using, as the outsides appear to be different from the center piece.

The technique is called "sanmai" in Japanese. It is a high carbon steel center layer clad with two layers of a low carbon steel. There's nothing rare or unusual about this. Hobbyist and semi-professional smiths do this every day in the US. You can see this and other more involved techniques for making even sharper blades on the History Channel TV series "Forged in Fire" in the US and on KZfaq. There are many KZfaq channels showing various blade forging techniques.

why?

@@bwang5176 because if you make it too brittle, the cutting edge will surely chip.

@@bramweinreder2346 easy, buy a block of 1095, temper it to around 50 or 60 HRC, fine grind the edge with a 3000 grit stone and boom. A knife that will last for generations if you oil it once and whole and clean it after use and don't leave it in water. But that's leaving out where the real skill actually come in, the level of the grind, the geometry of the edge, the balance resulting from tapering. These take years to master. Granted it's China we are watching here so it's hard to tell what steel was used, nearly any steel can be tempered but we weren't shown it's flex or durability merely that it cuts fish. If these guys wanted to impress I wanna see it's limits.

You can put an edge like that on almost anything but a really well forged blade will hold that edge.

@@johndouglass3691 and with modern steel that's unbelievably easy these days. Just gotta know who's making fakes.... China sadly so that's ironic. Heck 1095 steel knives are readily available at most stores in my area you just gotta remember they require special attention and service to prevent rust but beyond that they are exceedingly sharp and can retain that edge a few good years if you treat it like a hammer on bone regularly lol.

Thank you iTravel for posting this, at least I got to see it vicariously :)

A straight razor made in Japan from blue steel tamahagane costs 10,000 USD. They can make anything designer made steel powder where each individual grain is tailor made then sintered at high temperature and pressure. Today's metallurgy is a world start and unimaginable. 3% carbon, 3.5% chromium. 1.6% Vanadium 1.2% molybednum. The grain structure is tailor-made. Heat treatment is differential and targeted.

@@pvajit1109 BFS. You can purchase a good Katana for $10,000.... I'm pretty sure you meant ¥10,000. Especially being River Razor 14's ( arguably the best straight razor in the world ) are $300-$400.

probably some kind of mild steel
