ABSTRACT:
A hand operated cutter for cutting insulated wire of fine guage ranging in size from 24 to 32 American wire gauge. The wire has a central cylindrical metal core of copper, which may be unplated or covered with a nickel, silver or tin plating. The wire core is encased in an annular layer of plastic insulation. The cutter includes a pair of elongated members pivotally connected to each other intermediate their ends to provide handles at one end for manual manipulation and cutting blades at the other end. Each cutting blade has a cutting edge facing the cutting edge of the other blade. The cutting edges are movable into alignment with each other upon closing action of the handles. Stop means are located adjacent the cutting edges to prevent the cutting edges from contacting each other upon closing action of the handles. The stop means provide a clearance between the cutting edges of the blades which is sufficiently small to permit the cutting edges to penetrate the wire core of the insulated wire and to reduce the effective cross-section of the insulated wire at the areas of penetration to bring about autogenous separation of the insulated wire.
