ABSTRACT:
A knife blade has an edge provided with a recessed portion of a wavy profile and extending from the heel to the tip of the blade. The recessed portion of the edge is composed of a plurality of thick segments and thin segments. The thick segments press against the sides of an incision of the cut surface such that the thin segments and the cut surface form a plurality of gaps to accommodate air or fluid so as to prevent the sides of the incision of the cut surface from attaching to sides of the edge.
