Wire Cutters: Diagonal Pliers Forged with Hardened V-Edged Jaws

Diagonal pliers cut wire by pressing two V-shaped edges into it until it splits, not by shearing like scissors. The edges sit at an angle to the joint rivet, which gives them their name, and the jaws must be hardened or steel wire dents them. Forge two halves from tool steel, rivet them, grind the edges and harden the jaws. The picture: the jaws and joint of a modern pair; its handles are dipped in plastic, ours are bare steel.
