So I've been thinking about trying san mai lately and I've got a few questions. If you were to have your High carbon steel in the middle and one piece of, say 440 stainless for example on both sides. Do you have to weld the 440 onto the high carbon or could you wrap some high temp wire really tightly around the steel and put it into the fire, then after its really hot start pounding on it with the hammer?
Also, could you heat the high carbon up really hot then put the 440 on and start pounding it? Do you have to heat up both pieces to have them stick together?
Get what im trying to say?
