ABSTRACT:
A bolt cutter wherein there are removably replaceable cutter blades supported in cutting relation by pivotally connected jaws and wherein the jaws are structured to transmit the force couple for cutting to the blades at opposite ends and at opposite sides. Pivotal movement of the jaws relative to each other is effected by a cam roll and cam groove interengaged by the lever handles connected to the jaws. The cam groove is structured to enable changing its contour to thereby change the mechanical advantage.
