Boning Knife (Debabocho) 

The boning knife, or deba hocho (debabocho) translates to protruding blade. As seen in the picture, the blade is long in width, and sticks out more from the handle. The boning knife is thicker and shorter compared to the sashimi knife, and is used mainly to fillet fish. The angle of the blade is steeper than most knifes to be able to get into the fish and lift the flesh.
