Hitachi Metals

Hitachi Metals has long been the benchmark for premium blade steel, supplying the high-carbon alloys at the heart of Japan's finest cutting traditions. Their Shirogami (white paper) and Aogami (blue paper) grades are renowned for exceptional purity, giving knife makers precise, predictable heat treatment and outstanding edge performance. Shirogami excels where razor sharpness is the priority, while Aogami's alloyed composition offers greater toughness and wear resistance for demanding use. When the steel matters as much as the craft, Hitachi is the choice of serious bladesmiths worldwide.
