ABSTRACT:
Cutting dies are mounted for parallel movement in a scissors-action handle assembly employing pivot pins mounted both forward and rearward of the pivot axis of the handles, and one of the engagement openings for a pivot pin in each die is longitudinally extended for necessary clearance. The cutting edges of the two dies are at one longitudinal end of the tool extending beyond the portion of the dies between the two pivot pins. Parallel action is guided by a pair of guide pins longitudinally spaced and to the maximum extend possible located in the plane of the die cutting edges. A compression spring is centrally located between the guide pins to bias the dies to open position. When the dies are of the kind adapted to trim venetian blind slat ends, one die aligns the blind slat by transverse ribs to the cutting edge. The corners between the cut edge and the transverse edges of the slat are cosmetically blended for visual acceptability through provision for a small tangent angle at the union of the corner and the transverse edge.
