Artistic Wire Wire Straightener Tool makes it easy to straighten wire that has been worked. Put the rollers in your hand in the open position with each of the rollers side by side. Lay the wire in the center of the open tool, 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 nylon rollers to straighten. May need to pull through a second time for highly bent wires.
