One of basic techniques that every jewelry maker needs to know is how to straighten bent wire and headpins. Most likely the wire you purchase, such as sterling silver wire, gold filled wire and Artistic Craft Wire, will have been rolled into a coil on a spool. This sets the wire into a curl shape. Also, delicate headpins can be bent during transit. And of course we all make mistakes from time to time that need undoing.
Straightening wire is most easily accomplished using a Nylon Jaw Chain Nose Pliers.
Simply draw the wire through the nylon jaws while gently holding the pliers closed. Repeat this a few times until your wire is straight. The nylon jaws will protect your wire from nicks and scratches. And although the nylon tips should last awhile, they can be replaced when needed.
