Filling file teeth with this chalk is an age old "Gunsmith Kink"(R) to prevent "pinning", the buildup of metal chips in the teeth of the file. It increases the effectiveness of the file, extends file life, and produces a smoother, more professional finish. Metal removal is faster and easier, too. An inexpensive time and money saver. For superior results, use file chalk along with a good file card, listed elsewhere. Mfg: Brownells SPECS: 4" (10.2cm) long, 1" (2.5cm) diameter 2 pieces per tube.
