Abstract
An apparatus and method are provided for cutting corrugations into the resharpened blade of a scissor. The apparatus comprises a rotatable corrugating wheel. The peripheral annular circumferentially disposed edge of the wheel defines a corrugating surface that is configured to abrade the sharpened edge surface of the scissor blade. The corrugating surface is formed by a substantially uninterrupted ridge that helically winds around the entire circumferential edge of the corrugating wheel wherein adjacent windings of the ridge are separated by a substantially uninterrupted recess that helically winds around the entire circumferential edge of the corrugating wheel. The corrugating surface can be formed in the circumferentially disposed peripheral annular surface of a circular steel disc that has been coated with a fine diamond coating or a fine ceramic coating or a combination of the two. Alternatively, the corrugating surface can be formed in the circumferentially disposed peripheral annular surface of a circular disc formed of aluminum oxide.
