Aogami-Super Carbon Steel | Blue Super Steel
Aogami-Super (Hitachi Metals Ltd.) is one of the greatest Japanese Carbon Steels. In addition to containing more Carbon, Chromium and Tungsten than Blue Steel No.1, it also includes Molybdenum. It has very good edge sharpness and excellent edge retention, but is also capable of attaining high hardness without being brittle. Consequently, many knife enthusiasts rate Aogami Super as one of the very best High Carbon Steels in the world.

Kurouchi Finish, the unprocessed (black) part on the top side of the blade has already developed a dark patina, which protects the blade and gives it a traditional Japanese look.

The Japanese term “Nashiji” (English: Pear skin pattern) refers to the result of a technique that appears to leave the surface finish of a blade looking unfinished and rustic.
