Flush cutters are wire cutters ground to the apex of the cutting edge on one jaw side, for a flat cut that requires less finishing. Engineered to shear-cut up to 20 gauge (.8mm) soft wire. Suitable for silver, gold, copper, aluminum, and softer grades of brass and steel wire or thin sheet. Not recommended for memory wire, flex wire, and harder steel. Features: Rockwell hardness 54C tool steel blades, a return spring that minimizes hand motion, and nonslip hand grips. Narrow tip allows for access to small areas. Black finish on upper cutting surface helps reduce eye strain. Perfect for jewelers using narrower gauge wires in weaving, wire crochet, chain-making, filigree, enamel, and scrollwork techniques.
