ABSTRACT:
A manual sheet metal cutter (10) with a movable upper blade (12B) laterally offset from and integrally formed with a lower movable handle (12A) pivotally connected to, and sandwiched between, a stationary blade member (14) on the offset side of the movable blade (12B) and a stationary handle (16), of which are all pivotally connected together by a single fastener (11) defining a pivot axle. A rearward extension (14A) of the stationary blade (14B) defines an alignment section which bears against a mating alignment portion of an intermediate section (12C) of the movable blade member (12) to maintain the blades (12B, 14B) in correct cutting relationship. The fastener (11) enables pivotal adjustment of the angle of the stationary handle member (16) relative to the stationary blade member (14B), and an arcuate lower edge (14C) of the stationary blade member (14) defines a rocker to facilitate rocking, cutting movement.
