What Is a Third Hand Used for in Jewelry Making?

The third hand is an indispensable tool for securing items while they are soldered. The weighted base serves as an anchor while the hinged joint secures the interlocking tweezers in place with a tightening screw. The interlocking tweezers hold the item until you squeeze them to release it. This frees you to use both hands while soldering just as if you had a third hand!

Amazon has them on their website. Some third hands use alligator clips, however these are not nearly as secure as the locking tweezers.
