The IRWIN VISE-GRIP PowerSlot High Leverage Lineman’s Pliers feature a curved slot design, which provides 50% reduced cutting effort* when making a cut. Traditional high-leverage pliers have a trade-off between cutting force and handspan, but this technology minimizes that trade off. Complementing this high leverage design, the pliers feature 60CrV Steel, high-tech laser hardened cutting edges, and superior corrosion resistance**, offering a balance of high performance, durability, and cutting power.
