ABSTRACT:
A shearing tool has a fulcrum shaft, a first blade rigidly attached to the fulcrum shaft, a first element also rigidly attached to the fulcrum shaft and spaced apart on the shaft from the first blade, and a second blade contiguous with a second element, the second blade pivoted on the fulcrum shaft at one end of the blade, and between the attachment positions of the first blade and the first element such that relative rotation of the first and second elements causes relative rotation of the first and second blades producing a shearing action.
