Round Your Wire Tool is used to make sharp ends of cut beading wire smooth, for example in hand-made ear wires.
To use firmly insert the cut wire end into the cup. While pressing the wire firmly into the cup, twist the wooden handle back and forth. Stop twisting occasionally to look at the wire end. Continue to twist until the end is smooth and rounded.
The 1,2 cup bur fits wires up to 22GA (0,6mm thick)
Recommended for soft type wires like sterling silver, copper and brass
