The KNIPEX High Leverage CoBolt Fencing Pliers are designed with reduced cutting-edge hardness to allow more pressure on the sides of the cutting edges (e.g. for making fences). The precision cutting edges will cut soft and hard wire. Cutting capacity: maximum 4 mm for hard wire. Cuts material like bolts, nails, rivets, etc. up to 5.2 mm Dia. Exceptional cutting performance with minimum effort because of new lever action design providing a 20:1 ratio. Cutting edges are induction hardened, cutting edge hardness approximately 62 HRC. Made of chrome vanadium heavy-duty steel forged, oil-hardened.
