Tweezers, Bead Holders and Third Hands from Rings & Things.
Tweezers are often used to help you tie knots in fine cord, and have many other jewelry-making applications.
Nylon-jaw tweezers have an indent to gently hold delicate beads.
"Third Hands" are most commonly used for soldering, but are also "handy" for beading, knot tying, wire-working, and any time you need an extra hand. (See Soldering Tools for additional 3rd Hand tools.)
