Product Description Offering two stage sharpening and a compact design, the Double-Sided Diafold Sharpener is as strong as it is versatile and makes a great addition to your wet stone sharpening kit. Two different grits are combined to create a lightweight honing stone sharpener. Featuring a continuous surface that can be used for small or pointed edges, the fine diamond (25 micron / 600 mesh) is specialized for honing any blade or chisel to a razor sharp edge. On the opposite side, the coarse diamond (45 micron / 325 mesh) is specialized for quickly restoring neglected edges. Measuring 9.5" open, 5" closed, and featuring folding plastic handles that protect the sharpener when not in use, our sharpening system boasts unmatched portability and durability. Wherever you go, you can sharpen any edge in a fraction of the time required by conventional stones -- use as a lawn mower blade sharpener. No messy oils are needed either -- sharpen dry or with water. The durable construction will provide years of consistent performance and reliable service.
