These parallel pliers have nylon jaws with one jaw being convex and the other concave. Use them for bending and forming bracelets, wide bands or other rounded shapes. 140mm (5-1/2") long parallel pliers with springs. Non-marring nylon jaws are safe on all kinds of metals. Jaws can be further shaped with a coarse file or burs. Very nicely made in Pakistan.
The nylon jaw snap in half a shot off like a bullet, wear eye protection!!! Had to throw away the rest of it which was still in great shape, no replacement jaws available. These would get a 5 star if they would weld on or attach a steel backing to the top of the nylon jaws to stop the breakage. On my second pair, a must have for bending bracelets! wear the eye protection when using!
