Abstract

My invention relates to a hand operated notch cutting tool that will notch woven fabric, pliable or other thin material.

Claims

1. A hand operated notch cutting tool comprising an upper element and a lower element, said upper and lower elements being movable relative to each other, said lower element having an aperture therein, said aperture being defined in part by beveled cutting edges, said edges extending rearwardly from an apex to define a triangular notch shape in part, the upper element having a triangular shaped portion with some of the edges thereof being beveled to form upper cutting edges wherein upon relative movement therebetween, the upper cutting edges coact with the lower cutting edges to sever a triangular piece of material therebetween, the severing beginning at the apex and extending rearwardly to notch material placed between the upper and lower elements.

2. The tool as defined in claim 1, wherein the lower element has a tapered edge thereon to facilitate moving the element under material to be notched.
