Lineman Pliers are heavy-duty, side-cutting pliers, also known as combination pliers or side cutters, which are designed for all regular wire-cutting needs. They have gripping jaws, a cutting edge, and insulating handle grips that reduce (but don't eliminate) the risk of electric shock from contact with live wires.
