ABSTRACT:
A cutter for repeatedly cutting identical size pieces from a larger sheet of a semi-brittle and semi-rigid material includes an outer jaw affixed to a base and an inner jaw affixed to an arm that is resiliently connected to the base. The upper jaw includes a non-planar cutting edge that initiates the cut simultaneously at two locations located respectively on the right and left sides of the inner jaw and approximately midway between the front and rear of the inner jaw so as to produce a progressive scissors-like cutting action that proceeds simultaneously both forwardly and rearwardly from the aforesaid two locations and continues along the desired path.
