Abstract: A cutting apparatus used primarily to cut bolts or other cylindrical articles employing a source of compressed air to force a pair ofjaws together. The apparatus includes a handle provided with a trigger and a main body portion including a pair of laterally moving jaws. Compressed air will flow through the handle portion into the main body portion, thereby forcing a diaphragm downward forcing a piston to move in the direction of the jaws. A gear cam would force the proximal end of the jaw assembly outward, thereby forcing the jaws inward against one another, thereby cutting the cylindrical article.

Abstract: A lightweight, portable animal dehorner has fixed and movable cutter blades mounted in a common frame, the movable blade being driven toward and away from the fixed blade by an air brake chamber connected to a source of air under pressure, and a hand grip supports the air brake chamber in driving relation to the movable blade. A receptacle for severed horns may be attached to the cutter blade frame.
