Abstract
A sharpener for a serrated knife having a plurality of ribbed cutting edges interspersed with concave cutting edges, the sharpener consisting of an elongated abrasive sharpening member having a longitudinal axis and a peripheral surface, a ribbed configuration on the peripheral surface extending longitudinally of the longitudinal axis for slidably engaging the ribbed cutting edges, and a convex surface on the peripheral surface extending longitudinally of the longitudinal axis for slidably engaging the concave cutting edges.
Claims18
A sharpener for a serrated knife comprising a single elongated sharpening member having a longitudinal axis and a peripheral surface, a ribbed configuration on said peripheral surface extending longitudinally of said longitudinal axis, a convex surface on said peripheral surface extending longitudinally of said longitudinal axis, said ribbed configuration being circumferentially spaced from said convex surface by a circumferential portion of said peripheral surface which is of a different configuration than said ribbed configuration and said convex surface.
