Abstract:

An artist's paintbrush having bristles selected from the guard hair of the tail of a mink. In fabrication, hair is removed from the tail of the mink and the guard hairs are separated from the undercoat, which consists of soft and woolly hairs, preferably by brushing with a wire brush. The guard hairs which remain are selected into shorter and longer guard hairs. The shorter guard hairs are formed into a relatively thick body portion. The longer guard hairs extend beyond the shorter guard hairs to provide a paintbrush capable of painting simultaneously a plurality of extremely thin lines. The mink guard hairs are secured to a ferrule which, in turn, is joined to a wooden handle. The handle has a slim outer portion into which the ferrule is fitted. It has a relatively wider middle portion to provide for easy gripping and a wider rear portion ending in a flat pallet. The pallet may be used for spreading paint.
