The CoBolt(R) cutters with reduced cutting edge hardness to allow more pressure on the sides of the cutting edges (e.g. for making fences) Induction hardened cutting edges (approx. 62 HRC) for cutting soft and hard wire Cuts materials like bolts, nails, rivets, etc. up to 5/32" dia. for hard wire Exceptional cutting performance with minimum effort because of lever action design Gripping surface below the joint for gripping and pulling wires with a diameter from 3/64" Recess in the blade allows easier cutting of thicker wires, the wire won't slip out Chrome vanadium heavy-duty steel; forged, multi stage oil-hardened
