This Italian made 5" (125mm) cutter is ideal for cutting soft wire, such as sterling silver, up to 16 gauge. The maximum cut is 1.3mm copper wire. It is not suitable for cutting memory wire, flex wire or steel wire. Shear-action creates a flush cut which requires less finishing. Made of high-grade tool steel, the cutting blades feature a Rockwell hardness of 58 so they will efficiently cut metal over a longer time than standard cutters. The comfortable ergonomic handles help reduce hand fatigue.
