ABSTRACT:
The cutter of my invention is a unitary device that does not require a utility knife, only a blade. The cutter exposes twice the blade length of a conventional utility knife, i.e., approximately 2.2 inches. The blade can be extended into the insulation over 4 inches. The cutter has a blade guard (to keep fingers out of the way, etc.). The cutter also has a safety mechanism to guard against accidental exposure of the blade (you have to grip the tool by the handle to allow the blade to be exposed). The cutter also has an added leverage point directly in front of the grip to increase the amount of pressure you can exert on the insulation. This cutter compresses and cut in one continuous motion, i.e. the same motion does both compressing and cutting.
