Aogami-Super (Hitachi Metals Ltd.) is one of the most outstanding Japanese carbon steels. In addition to containing more carbon, chromium, and tungsten than Blue Steel #1, it also includes Molybdenum. It has excellent edge sharpness and edge retention but is also capable of attaining high hardness without being brittle. Consequently, many knife enthusiasts rate Aogami Super as one of the world's very best high carbon steels.
