A pair of pliers, wire cutter (to.060"), and wire twister - all in one. You can easily grip, twist, shape, and snip wire without searching for different tools. Twisting safety wire is easy: grip the wire, lock the jaws and pull out the spring-loaded end knob (pulling turns the pliers). Uniformly and tightly twists the wire every time. Hardened, tempered steel; 10 1/2" long.
