Rotary shaving cutter with alternatively arranged plates

A wafer shaving cutter comprising:

• a plurality of annular first plates, each having opposed major faces and a plurality of circumferentially spaced, radially extending teeth formed thereon, each tooth having major opposed faces, an outer end land, opposed side lands in a predetermined gear tooth profile, and cutting edges formed at a juncture of the side lands and the major faces, each first plate having an identical first width between opposed major faces;
• plurality of second annular plates alternatingly arranged with the plurality of first plates, each of the plurality of second plates having opposed major faces and a plurality of circumferentially spaced, radially extending teeth formed thereon, each tooth having opposed major faces, an outer end land, opposed side lands in a predetermined gear tooth profile;
• the teeth in the first plates have opposite pairs of diagonally opposed cutting edges, each formed between one adjacent major surface and one side land of each tooth;
• and
• an included angle between the adjacent major surface and adjacent side land of one pair of diagonally opposed cutting edges being unequal to the included angle between the adjacent major surface and adjacent side land of the diagonally opposed pair of cutting edges;
• each tooth on each of the first plates aligned with a tooth on adjacent first plates to form a composite tooth with grooves therebetween;
• and
• means for joining the plurality of first plates and the plurality of second plates into a fixed, unitary arrangement in which the teeth on the first and second plates extend helically along the shaving cutter.
