It sharpens in a fraction of the time that traditional files require. Fine diamond (25 microns/600 mesh) for a razor-sharp edge. Length 11.3 cm, width 19 to 6 mm. Dimensions: 24.1 cm open, 12.7 cm closed. Sharpening with diamonds is quick and easy. No greasy oils required; sharpen dry or with water.
