ABSTRACT:
A hand-operated cutting tool in the form of shears having handle portions and cutting portions pivoted so that the cutting portions may be rotatably moved toward and away from each other. The cutting portions each include a pair of cutting edges angularly disposed with respect to each, providing an included angle there between which is obtuse. As the cutting edges are rotated toward each other, a first portion thereof are brought into sliding, overlapping contact for shearing a flexible material such as flexible ducting and a second portion thereof are brought in sliding, overlapping contact for cutting wire.
