Deba bōchō

Deba bōchō (Japanese: 出刃包丁) — "fish-preparer" — are a style of Japanese kitchen knives primarily used to cut fish, though are also used occasionally in cutting meat. Debas have wide blades and are the thickest of all Japanese kitchen knives and come in different sizes — sometimes up to 30 centimetres (12 inches) in length and 10 millimetres (0.4 inches) thick — but usually considerably shorter, normally between 12 and 20 cm (5 and 8 in) long with a blade between 5 and 7 mm (0.2 and 0.3 in) thick. The larger form of knife is called an hon-deba, ("true deba") whereas the smaller form is a ko-deba.

The deba bōchō first appeared during the Edo period in Sakai. Following the traditions of Japanese knives, they have just a single bevel to the edge — with an urasuki hollow back on premium blades — so generally come in just right-handed versions, but left-handed ones can be found in specialist shops. It is designed to behead and fillet fish. A deba's thickness, and often a more obtuse angle on the back of the heel allow it to cut off the heads of fish without damage. The rest of the blade is then used to ride against the fish bones, separating the fillet.

Maintenance

Traditionally, deba knives are made of carbon steel, which needs regular maintenance and oiling to prevent rust. However, many modern knives are also available in stainless steel. The carbon steel blades can be honed into a sharper cutting edge. The deba is not intended for chopping large diameter bones of pork or beef.
