Abstract:
1. A method of manufacturing a paper shredder blade set using a notched blade having a substantially round and generally flat shaped body, a first and second opposing substantially flat sides, a center hole adapted to receive a cutting arbor, at least two knife edges disposed on a periphery of the body, and at least two notches with each notch extending from a point in the body through the periphery and through the substantially flat sides, and a mating blade having a substantially round and generally flat shaped body, a first and second opposing substantially flat sides, a center hole adapted to receive a cutting arbor, and at least two knife edges disposed on a periphery of the body; comprising the steps of: placing the first substantially flat side of the notched blade in contact with the first substantially flat side of the mating blade such that each of the knife edges on the notched blade substantially align with a corresponding knife edge on the mating blade; aligning the knife edges on the notched blade and the mating blade forming a blade set with a V shaped blade; applying force to the second side of the mating blade in a location generally opposite the notch in the notched blade such that an amount of the material from the body of the mating blade is disposed within the notch of the notched blade such that a portion of the material in the notch remains forcibly attached to the mating blade and the notched blade and the mating blade are substantially secured to one another.
