This is a wire twisting tool. I have a piece of wire looped over a nail or you could use a bench vise. I'm going to open the jaws of my tool and put the loose ends of the wire in the jaws. I'm going to give this a good squeeze. and pull this down to lock that in place. And I'm going to release this tool as I pull back on this knotch. And then I'll grab again before I release and repeat that until the twist is tight as I want it to be. One more pull and to release the lock I'm just going to give the tool a squeeze. Now I have a nicely twisted wire. Go to Beadaholique.com for all of your beading supply needs!
