Maguro Bocho Tuna Knife

An extra-long knife designed for breaking down and portioning large tuna.

The maguro bocho is one of the most dramatic knives in Japanese cuisine. Its blades run from about 390mm to well over 700mm, giving the length to cut a whole tuna into loins and blocks in long, controlled strokes. These knives are used at fish markets, by tuna wholesalers and at high-end sushi restaurants that buy whole fish.

Our maguro bocho are made in stain-resistant Ginsan, including mirror-polished versions with triple silver ring ebony handles in sakimaru takobiki, yanagi and yanagi kiritsuke styles, and a Hongasumi Blue Steel #1 blade of 750mm.
