Metal Scratch Brush set of 3 in Fiberglass Steel and Brass
This set of 3 scratch brushes gives you a nice variety of soft, medium and hard bristle scratch brushes. The metal ferrules or bristles are made of fiberglass (soft), brass (medium) and steel (hard) so you have the ability to work with delicate watch parts and not leave deep scratches or cause damage, and they also can remove tough rust from metals or clean drill bits and burs of debris.
