🔧 What it does & how to use

A file burnisher is a hand tool used by watchmakers and clockmakers to smooth, grind and polish small metal components such as pivots, staffs, pinions and other repair parts, removing tool marks and raising a bright, hardened finish. The twin type gives two working faces on the one tool, letting you move from a coarser grinding action to a fine polishing pass without swapping tools. To use, secure the part in a pin vice, lathe or by hand, then draw the burnisher's face steadily across the surface under light, even pressure, working along the metal until it takes on a smooth, polished finish. Suited to both hobbyist repairers and professional watch and clock workshops.
