D2 CROWN SERIES - D2 steel is an air hardening, high carbon, and high chromium tool steel possessing extremely high wear resisting properties. D2 steel is commonly used in the machining industries to manufacturer dies and punches that repeatably cut other metals. It is an extremely tough and durable steel. The high chromium content provides good corrosion resistance, (but it can and will rust if it is not properly taken care of). The blades are heat treated to a 62 Rockwell hardness and are guaranteed to retain their factory edge for extended periods of heavy use. When it does come time to re-sharpen, this high carbon tool steel will hone to a razor edge. Only a few commercial cutlery manufactures offer D2 steel blades. D2 steel is primarily used by the best custom knife makers. Anyone whom has ever used a SILVER STAG D2 steel blade in the field, raves about the knifes cutting ability, durability, and edge holding properties. D2 is the best steel you can use for a hardcore, working knife! The Crown Series features North American Deer and Elk antler crown/burr handles
