Abstract
An improved parallel action die cutting hand tool having a pair of scissors-action handle levers pivoted on a transverse pivot axis, so that the handle levers operate in a plane. The hand tool includes first and second die cutting jaws connected to the handle levers for parallel movement toward and away from each other. The hand tool has a pair of guide pins extending between the die cutting jaws and slidable with respect to at least one of the jaws. Each pin lies outside of and parallel to the plane of the handle levers. A die plate, held on one of the jaws by a pair of ribs, has curved corners that meet the ribs at a tangent angle of substantially zero degrees. In an alternate embodiment of the invention, the guide pins are spaced apart, lying in the plane of the handle levers, and located on opposite sides of the cutting edges. In another alternate embodiment, there is a single guide pin only, lying in the plane of the handle levers and located approximately midway between the forward pivot pins and the transverse pivot axis.
