This easy-to-use straightener tool makes it a breeze to straighten wire that has already been worked. Put the rollers in your hand in the open position with each of the rollers side by side. Lay the end of a piece of wire that requires straightening on the three rollers, then move the rollers until they form a triangle with the wire in the center. Grasp the rollers in one hand holding tightly, then pull the wire through the rollers to straighten. If your wire is really bent, you may need to pull your wire through a second time. The nylon rollers help to keep your wire coating intact.
