Abstract

An improved pliers having a first and second member. The first member includes a jaw operatively connected to a first handle, and the second member includes a second jaw operatively connected to a second handle. A slot is located in one of the members between the jaw and the handle. A pin in the other member extends into the slot and is secured therein to hold the members together while permitting relative motion between them. The slot may have different shapes but must be long and wide enough to allow the pin unrestricted motion. A projection extends from one of the members and engages a pivot area which may be a surface or a notch on the other member. In two embodiments of this invention, two pivot notches are used to give two different ranges of motion to the jaws. Different shapes of jaws may be used for specialized purposes, such as, opening pipe clamps or removing oil filters. The projection and pivot notches may be placed at different locations between the pin and the jaws to give a different mechanical advantages.
