- Blade Shape: Deba knife - Blade Material: Steel - Handle Material: Wood This is a small Deba knife that my parents' home kept, purchased during the Showa era. It has a Tosa stamp. The blade has been sharpened by a professional sharpener. Total length: 22.5 cm Blade portion: 11.5 cm x 3 cm I think it will be useful for filleting small fish. As it is a bladed item, I will carefully pack and ship it. There is a "650" on the handle, but I don't know if that's the price.
