Ichizo (市蔵) is a blade brand from the Banshu region of Japan, with a tradition of quality craftsmanship. This is a Tosa Kurouchi Santoku (土佐黒打ち三徳) — a double-bevel all-purpose kitchen knife in the traditional style of Tosa (present-day Kochi Prefecture), one of Japan's oldest blacksmithing regions. The blade is forged from Aogami (青鋼, Blue Steel) in warikomi construction, and left with its kurouchi (黒打ち, "black forged") finish — the dark, hand-hammered scale straight from the forge, rather than polished to a mirror shine. It is a blade with real character, made for cooks who want to work with a traditional carbon steel edge.

Please Sharpen Before First Use

This knife ships with a factory edge. It will cut as shipped, but it is not brought to its final, full sharpness at the factory — traditional Kurouchi blades like this one are meant to be finished on a whetstone by the person using them. Take some time on a whetstone to bring up your own edge on the Aogami steel, and you will be rewarded with the kind of sharpness this steel is known for.
