  • Wire cutter structure for multipurpose tool
    Patent number: 5826338
    Abstract: A multipurpose tool may have several tool elements which pivot into storage positions in profiled handles attached to one of a pair of pliers jaws. A wire-cutter portion of each pliers jaw includes a sharp edge and a notch located at the throat of the pair of jaws, adjacent the sharp edge. The notches face toward each other to support and shear wire, but the bottoms of the notches are prevented from passing each other so that bulging material at the bottoms of the notches does not cause the jaws to bind against each other.
