Abstract
A shearing cutter for wire and cable, particularly insulated metal wires and wire bundles as used in electrical and electronic circuits, is constructed in the form of a hand tool with elongated, hinged handles adapted to develop shearing forces between cooperating blades cantilevered beyond the hinge point from each of the handles. The blades are symmetrical in shape and define a substantially circular opening between semicircular bights sharpened into cutting edges in each of the blades. A wire or cable is maintained in a central location with respect to the aforementioned bights by the enveloping nature of the cutting edges, resulting in a clean, uniform shear plane.
Claims5
A hand tool for cutting wire, cable and the like comprising:
- a pair of cooperating, elongated members pivotally secured at a locus which separates said members into a pair of handles and a pair of primary cutting blades, said members being mutually pivotal between an opened and a closed position;
- each of said primary cutting blades comprises an inner sharpened edge, an outer blunt end having inbound and outbound edges, a back face extending from the sharpened edge to the inbound edge of the blunt end, and a front face extending from the sharpened edge to the outbound edge of the blunt end;
- each of said inner sharpened edges has a substantially semi-circular configuration and, in combination, define oppositely disposed curves;
- each of said back faces is substantially flat and said back faces are disposed in abutting relationship and traverse each other in such relationship;
- and
- each of said front faces comprises a curved ramp rising from the semi-circular sharpened edge and extending to the outbound edge of the blunt end, with the gradient of each ramp being substantially the same and in the range between 33% and 50%.
