(FIG. 1) shows an improved bolt cutting tool comprising left and right cutting jaws (10) that are closed by handles (12A and 12B). As, handles (12A and 12B) are separated, jaw (10) opens to allow the material to be cut to enter. As handles (12A and 12B) are closed, utilizing threaded rod (14) to draw them closed, the cutting edges of jaw (10) close (FIG. 2). This substantially enhanced mechanical advantage allows any user to produce the needed cutting force. It is not limited by the physical strength of the user as with conventional bolt cutters. Another advantage of the embodiment is a bolt cutter that has much shorter handles, is less cumbersome and can be manufactured with a more compact construction. Cutting of relatively large hard work-pieces, such as bolts, locks or reinforcing bars can be done with relative ease. (FIG. 4A and FIG. 4B) show embodiments where threaded rod (14A), be manually closed by operation of a ratchet and in another embodiment, by operation of a rotating handle (FIG. 1).
