ABSTRACT:
A manuallly operated tool, wherein the manipulation of handles at one end of the tool results in a corresponding movement in jaws at the opposite end. The tool includes two handle elements, wherein each handle element has a first end and a second end. A first pivot joins the two handle elements together so that the distance between the first ends of each handle element and the first pivot is more than twice as long as the distance between the second ends and the first pivot. Two jaw elements are also provided, Wherein each jaw element has a working head end and an opposite tail end. A second pivot joins each of the jaw elements together so that the distance between the tip of each working head end and the second pivot is at least twice as long as the distance between each tail end and the second pivot. The jaw elements are pivotably connected to the handle elements, whereby the length of the handle elements in proportion to the jaw elements provide a mechanical advantage to the jaw elements of at least 2:1.
