Spyderco’s ceramic files are specifically designed for sharpening small, detailed tools like woodcarving tools, gouges, and dental devices. They are also used by gunsmiths for trigger jobs, deburring, and detail finishing. This versatile slip (teardrop-shaped) file features a large radius, a small radius, and two flat sides, making it ideal for sharpening, smoothing, and polishing woodcarving gouges, serrated edges, and other small cutting tools with complex shapes. It also includes a longitudinal groove for sharpening awls, fishhooks, and other pointed tools. Made from fine-grit high-alumina ceramic, the slip stone file is easily cleaned with household cleanser, a scouring pad, and water. Made in the USA and sold individually.
