These Long-Nose pliers are spring-loaded for self-opening action. The slim head design works well in confined areas. Jaws are knurled for sure wrapping and looping of wire. Curved handles provide greater tool control while the joint is hot-riveted for smooth action and no handle wobble. Made of the finest U.S. steel alloy, they are forged, precision machined, hardened, and carefully tempered for maximum strength.
