GPM440(Geruk) - PM martensitic stainless steel. High carbide volume with fine carbides. High wear resistance. Not that easy to put a sharp edge on it though. Base for this alloy was AISI 440C steel with added Carbon and Vanadium. Main issue with making knives out of it was low attainable hardness, around 56HRC. Sure, there are knives softer than that too, but for a knife made of supersteel it was too much of a trouble. Not sure if it is still made.
