I'm not really a knife maker as much as a knife projecter. I buy old used knives or blade of good quality but poor condition, and use the the old blades to make a "new" knife. Sometimes just "rehandle" them. Or sometimes regrind/reshape the blade depending on condition.
So I buy a large Marbles brand bowie blade on Ebay. Pics show a pitted blade. But when it arrived I am convinced that the blade has been in a fire. And possibly if not probably has lost it's temper. While attempting to clean it up, I notice that the blade edge develops thin "flashing" that I've never experienced on any other blade.
So I'm wonder if there is a way to heat treat it at home. I don't own a forge to heat it up. But I do own an Acetylene torch. Does it matter how you heat it up?
