The Scriber is a common tool that can scratch surfaces from mirror to glass to metal. The stone is a small tool intended to be put into a drill for use as a grinder. Due to the size and shape, it can be difficult to get a firm, comfortable grip, so we've made a handle. You're welcome!

The Krink Scriber is 5 x 3/8 inches. It includes a 10mm aluminum oxide stone round tip and can be replaced with any 1/8 inch shank tool.
