Deba / Fish Filleting

Deba are Japanese style kitchen carvers primarily used to cut fish, though also used when cutting meat. They come in different sizes, sometimes up to 30 cm (12 inches) in length. It is designed to behead and fillet fish. Its 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.
