Abstract

The tool has a pivoting triangular blade (4) for cutting paper. Contained cuts may be made with the tool, e.g. the internal cuts required to form a frame from a square sheet of cardboard. The blade is mounted with the short side vertical, the long side fixed to a handled (6) pivoting bar (7), and the hypotenuse forming an inclined cutting edge (12). The angle subtended by the short side and the hypotenuse, thus forms a point (8) which leads the cutting edge (12) into the workpiece and defines the start of the cut. The cutting edge (12) may have a convex curve and the short edge has a concave curve. The position of the blade (4) on the pivoting bar (7) may be adjustable.
