This particular model features extra-fine diamond (9 micron / 1200 mesh) to polish and refine a razor edge after sharpening with a coarser diamond. Consistent across all Single Sided Diafold Sharpeners, however, is their convenient size of 9 1/2" when open and 5" when closed. The folding plastic handles also protect sharpener when not in use. With the addition of a robust, micronized monocrystalline diamond surface, the Single Sided Diafold Sharpener can sharpen any edge in a fraction of the time required by conventional stones. No messy oils are needed either, allowing you to sharpen dry or with water. Complete with a durable construction that will provide years of consistent performance and reliable service, woodworkers, chefs and other professionals rely on the superior quality and versatility of DMT® products for proper tool maintenance.
