👍🤗🤔😉 They use meteoritic iron containing little carbon, so they take steps that saturate the surface with carbon and then fold and forge together and do it repeatedly many times until they reach about 0.8 to 1.0% carbon in the iron, which creates carbon steel. That hardening with a layer of clay on the surface and a typical wavy line on the border of the hard hardened part is a browned sequential hardening for one heating = hardening and tempering. The cutting edge is Martensitic in the core Pearlitic the more - closer to the back the more Ferritic - Pearlitic, so very tough. This description is simplified but at its core real. Japanese blacksmiths are masters. Hats off 👍🤗🤔😉💯%
