Exceptional cutting performance: 60% less effort compared to conventional high leverage diagonal cutters. The lever-action mechanism ensures an extremely favorable lever ratio with very little friction. The cutting force is about 20 times higher than hand force applied. Induction hardened edges cut soft, hard and piano wire. Cuts materials like bolts, nails, rivets, etc. up to 1/4" dia. Cutting edge hardness approx. 64 HRC. Micro-structured cutting edges allow easy cutting of large cross-sections. Gripping surface below the joint for gripping and pulling wires with a diameter from 3/64". Chrome vanadium heavy-duty steel; forged, multistage oil-hardened.
