Abstract
A pizza cutting apparatus and portions of the apparatus, and methods of forming the apparatus and of disassembly. The apparatus includes a simple frame assembly made from sheet metal, an actuator assembly and a cutting assembly. The cutting assembly includes a central hub, a number of attached blade and guard combinations, a shaft with a flange and an elastic band. Each blade includes two spaced apart openings, one to receive the flange and the other to be engaged by the band so as to restrain the blades mounted in the hub. Each guard includes perforations for easy gripping by an operator. A blade is removed by having the operator safely grip each guard to stretch the band so as to disengage the blade from the flange and then return and rotate the blade to disengage the blade from the band.
