The Deba is a knife designed for filleting fish. Together with the Yanagiba it is one of the most traditional knife designs found in Japan. This is a single bevel knife which means the bevel in on one side of the blade, most commonly the right side. Left-handed single bevel knives are available but not as common as right-handed ones. The back side of the deba is slightly concave which makes for a strong and screaming sharp cutting edge.
There are more then one styles and varieties of the Deba, depending on the specific task or production area. You will find all varieties on this page.
