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 Marine Plastic material in the handle is lightweight and comfortable. All of our Marine Plastic Handles are made from recycled ocean plastics reclaimed from the beaches of Tsushima. Our company wants to make an effort to help clean up the wasted ocean plastics and beaches and to do our best to leave a cleaner world for the next generation. Our process of making these handles is still underdevelopment, as such they sometimes are shipped with minor imperfections.
