ABSTRACT:
In the art of cutting dies for layers of deformable stock material such as plastic, the improved cutting means combination and method which includes a razor blade cutting edge mounted on a punch press opposite a supporting cutting surface having a slot matching the shape of the razor blade cutting edge. The cutting edge is applied with appropriate pressure to the stack of material in the area of relief provided by the slot so that a clean efficient cut is effected through the stack of material. Preferably the razor blade cutting edge is a single blade so that problems such as material hang ups caused by incomplete cutting are minimized and/or completely eliminated.
