ABSTRACT:
A mechanism for use in crimping and cutting tools and the like includes a resettable drive system which permits the user to selectively increase or decrease the angular opening between the tool handles at any fixed point in the operative stroke of the tool. The handles of the tool may thus be disposed at any desired angular relationship with respect to one another for operation either in close quarters or for more comfortable operation without sacrificing the lever advantage originally designed into the tool.
