Apparatus and method for corrugating resharpened blades

A method for grinding corrugations into a narrow surface forming one side of the cutting edge of a blade of a pair of scissors for which the cutting edge of the blade has been resharpened, comprising:

• using a motor to rotate a portable corrugating wheel at essentially a constant number of revolutions per minute, wherein the annular circumferential edge of the wheel defines a corrugating surface therein, wherein the width of the corrugating surface measures substantially less than the length of the blade of the scissors and said corrugating surface defines a plurality of alternating radially projecting, triangular shaped peaks and grooves that has a predetermined pitch;
• using a mechanical blade holder to hold the blade to be corrugated at a fixed angle with respect to the rotating corrugating surface of the corrugating wheel;
• placing the edge of the resharpened blade near the portion of the blade closest to the pivot point of the scissor, into sufficient grinding contact with the corrugating surface so that upon rotation of the corrugating wheel with the corrugating surface in contact with the narrow surface forming one side of the edge of the blade to be corrugated, the rotation of the corrugating wheel will cause the free end of the blade to be pulled in the direction toward the corrugating surface of the corrugating wheel as the corrugating surface of the corrugating wheel will grind new corrugations into the entire narrow surface forming one side of the edge of the resharpened scissor blade.
