Abstract

Abstract A hand tool having a handle with a concave blade at each end and a method for obtaining a skinless, boneless one piece fillet. The blade includes a linear shearing edge and a curvilinear shearing edge conforming to the rib cage of a fish, the edges converging to an apex. The apex of the blade may be inserted in a slit along the backbone of the fish terminating in a transverse slit at the tail. With the concavity facing toward the tail, the linear shearing edge bearing against the inner surface of the skin and the curvilinear shearing edge embracing the rib cage, the tool is moved from the head toward the tail to remove substantially all of the flesh portion of the fish with a plow-like action. The blades are mirror images of each other, one being suitable for use on one side of the fish and the other blade suitable for use on the opposite side of the fish.
