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.The traditional style of Japanese carving has a long history of simplicity and inspiration. Although this technique (Chokin) is gradually disappearing into history, we hope to do our best to let more people feel its beauty.This is a limited edition of our kitchen knives in collaboration with the carver Asamura Takao, whose over 50 years of carving skills make each piece look so spiritual. Each design has been polished for months, even a year or more.
