Its called memory metal because heat can get it to revert back to a previous shape. The hardness of the carbides does not matter much unlike with edge retention. When the blade gets messed up I just replace it. They represent the absolute best performers on the market in terms of their specific attributes. It would be interesting to try to develop a conversation between /geometry/edge retention/toughness, so we could say e.g. Heat treatment and edge geometry can mean more for knife performance than the specific steel used in the knife. I have a couple questions, not directly related to this specific post, that I wanted to ask publically so that others could find your responses as well, so here seemed as good a place as any. Each of these contributes to a knifes overall performance. Each test is done with 3 or more specimens to get a good average.
