Here is a new question about the making of Japanese knives (you can find the first two here and here).
According to many sources, the best Japanese knives are made in a traditional way with forge welding. However, I learned that forge welding is only for iron and low carbon steel, while the best knives are made of stainless steel (high carbon).
Would there be a way to heat stainless steel blades to melting so that they can be hammered using this forge welding, or should more advanced welding techniques be used? If so, could you give me an example?
