After reading how to temper in the oven, and then holding that temperature for 1 or 2 hrs, and then letting it cool, and then doing it again, I have to ask: how does treating with various methods in the forge while watching the colors change work? It seems that it is heated for just a few minutes and then quenched. Does the oven method create a better blade due to changes internally in the steel while the forge method just makes it less brittle?
