Pounce wheels are spiked wheels attached to a handle and fitted in such a way that it may be swivelled to follow around circles and curves or locked for straight work. Run the pounce wheel along the outlines of a drawing on a thin medium, such as paper, to perforate it. The image can then be transferred onto a surface with the use of a pounce pad and some pounce powder.
1/4'' diameter, 15 teeth per inch. Bevelled on one side to follow straight line.
