High leverage design requires 40% less effort compared to conventional combination pliers. Cross-hatched knurled gripping zone in the jaws provide for stronger gripping and pulling. Additional serrated gripping zone below the articulated joint for greater leverage. Cutting edges for soft, hard and ACSR wire. All insulated tools meet the requirements of ASTM F1505. High leverage means less force required because the rivet is closer to the cutting edge. Cutting capacity - up to 3/16" for medium hard wire and up to 1/8" for hard wire.
