  1. D2 is not semi-stainless. It is a tool steel when hardened will hold an edge like you wouldn’t believe. It is used mainly for stamping dies because it will “cut” steel a lot longer than other tool steels. If you harden it too much it does become brittle. The trick is to harden it to a low Rockwell on the “c” scale.
