Zig Zag Corrugating Parallel Pliers 140mm (5-1/2") long Jura by GRS These risers are purpose-built forThese 140mm (51 2") parallel pliers feature zig zag shaped jaws designed specifically for corrugating metal an essential technique in jewelry making and metalsmithing for adding texture and rigidity to sheet metal. The parallel jaw action ensures even, consistent pressure across the full width of the workpiece, producing uniform corrugations with every pass. Spring loaded handles keep the jaws in the open position at rest, reducing hand fatigue during
