These parallel pliers have wide steel jaws with one jaws that are V-shaped. Steel jaws can mar soft metals so try gluing leather onto the jaws for added protection. You can also cover the jaws with a thermoplastic like Jett Sett. Use these pliers for bending and forming wire and stock into sharp angles. 140mm (5-1/2") long parallel pliers with springs. Very nicely made in Pakistan.
