Abstract
A blade set for paper shredders is disclosed. In one embodiment, a notched blade having at least two notches in proximity to a central hole is brought into contact with a mating blade also having a central hole. Force is applied to the mating blade in such a fashion as to displace some of the body of the mating blade into the notches. This acts to substantially secure the blades together. In another embodiment, the notches are disposed on the edge of the blade and through the periphery. In yet another embodiment, one blade can have holes and not notches.
