Lindstrom RX Ergonomic long chain-nose pliers with smooth jaws. Model RX7890. These pliers were only used only or twice.
Recognized by jewelers and craftsmen worldwide, Lindstrom Pliers are unsurpassed in quality materials, design and performance. Lindstrom RX pliers represent the ultimate in performance, precision and comfort. With their exclusive Lindstrom BioSpring®, RX tools eliminate the effort overcoming ordinary spring tension, which increases as you apply pressure.
The BioSpring is an adjustable, replaceable plastic spring that controls and limits resistance as you apply pressure. To adjust the spring, simply open the tool, move the free end of the spring into the desired opening in the handle, and close the tool.
The flat interior surfaces of these pliers are ideal for opening and closing jump rings, flat-crimping and creating angled bends. The exclusive BioSpring® reduces spring tension during work which lessons fatigue and hand stress.
