Looking good from America, I send my respect to these artists in Taiwan. My first job at 15 years old was cleaning catfish at fish farm. And my trade is a welder and I love metal work, so I can relate to all of this...
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.
I wish there were subtitles to have the expert explain what the process were step by step.That is great work and skillsmanship. The blade is to be respected most definitely.
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 RU-vid. There are many RU-vid channels showing various blade forging techniques.
@@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.
I worked in Taipei City, Taiwan from March to June of this year and I REALLY wanted to see some of the local blacksmiths (being a blacksmith myself) but sadly 3 months is FAR too short of a time to to see even .00001% of what that beautiful country has to offer. Hopefully someday I can make it back there but I doubt that I'll get my employer to foot the bill again :(
I was thinking of pick up one of these long tuna knives, but I changed my mind, for it will bend upon side pressure. It's not as flexible as I first thought.
@@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.
Der Mann hört genau um welches metal es sich handelt da Wette ich! Alte gute Handwerkskunst ist durch neue mit Sicherheit nicht mehr zu ersetzen! Super der Mann 👍👍
The steel is high carbon high chromium and can be hardened to 65-67 HRC. Once sharpened, it will retain its edge and cut through bones like butter. The technology has changed with powder metallury and each grain of powder is made perfect, sintered to the shape and size then ground precise to the required edge. Amazing to see Titanium carbide deposition on edge as in turbine blades of a jet engine. Those knives are unbelievable.
If these Taiwanese and even Japanese artisans ever got into the business of straight razor manufacturing, they'd hit a worldwide market the likes they've never seen!
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.
