Hatsukokoro—meaning “Innocent Spirit”—works withindependent and mid-sized shops to offer Japaneseknives at accessible prices. The Kumokage (“CloudShadow”) series is crafted by Tosa makers usingtraditional hammer-forged, san-mai construction.

Each knife features a Blue #2 steel edge with a hardness of HRC 62±. Popular with cooks for its ability to take a very sharp edge and hold it well, Blue #2 is a carbon steel that can be sharpened readily. Its trade-offs: it can rust or discolor, so dry the blade after use and avoid leaving it wet.

Soft iron cladding and a distinctive Kurouchi and Damascus finish complete the knife’s traditional look. With an even edge grind, the Kumokage pairs Tosa craftsmanship with practical performance.
