Aogami No.2 (Hitachi Metals Ltd.) is made by adding Chromium and Tungsten / Wolfram to Shirogami No.2. This results in increased toughness and the production of hard carbide molecules which improve edge retention. Many knife users have noted that while Aogami No.2 is very similar to Shirogami No.2 in terms of edge sharpness, it has slightly superior edge retention.

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 handles on these knives are Octagonal Oak wood dye Japanese Lacquer (Urushi) that recalls the images of Japanese tradition.

The coating film of Urushi exudes a warm sense of intimacy when in contact with the skin that can almost be likened to the touch of an infant’s skin. With antibacterial and disinfectant properties, it is also provides an exceptional sense of security. urushi is a totally natural lacquer, and with use develops a distinct, deeply refined luster and texture which cannot be reproduced with chemically developed coating materials. This naturally fosters strong feelings of attachment and deference.
