ABSTRACT:
A cutting tool capable of cutting work pieces which are thicker than what comparably-sized conventional cutting tools are capable of cutting has a jaw with a cutting edge which does not completely abut or overlap over the full length of an opposing edge of a second jaw when the cutting tool is in its closed position. A resulting gap between the opposing edges varies from a maximum at the free end of the cutting edges to zero at a portion of the opposing edges where the edges abut one another. The cutting tool successively notches a work piece, and as the notch deepens, the work piece is advanced toward the abutting portion of the cutting edge and the opposing edge until it is finally severed. The jaws may be operated manually by hand levers or driven by hydraulic, pneumatic or electrical drive mechanisms.
