DMT Dia-Sharp 4in Diamond Sharpener Fine 600 Grit D4F

Sharpen with precision and reliability using the DMT Dia-Sharp 4in Diamond Sharpener Fine—a compact, professional-grade sharpening stone built to meet the needs of serious users. Whether you're honing kitchen cutlery, woodworking tools, or field knives, this fine-grit sharpener delivers consistent results with minimal effort. Crafted in the USA, the Dia-Sharp features a continuous surface of micronized monocrystalline diamond, electroplated onto a solid stainless steel plate. This design ensures a flat, even sharpening area that won’t dish over time and can handle repeated use across a wide range of edge tools.

The fine grit, rated at 25 microns (600 mesh), is engineered for refining and finishing edges. It’s ideal for touch-ups or the final stage of sharpening, leaving blades keen and ready for precision cutting. Unlike traditional whetstones, the Dia-Sharp works dry or with water—no oil is needed. This not only simplifies maintenance but also makes the sharpening process cleaner and faster. The diamond surface offers superior hardness and abrasion, allowing it to cut more aggressively and wear more slowly than conventional stones.

Measuring just 4 inches long and under an inch wide, this sharpener packs professional performance into a portable size. Whether you’re working in a workshop, out in the field, or in a compact kitchen, it’s easy to stow, quick to deploy, and dependable in all environments. The continuous diamond surface also makes it especially effective on small contact areas or pointed tools, where precision is key.

DMT’s commitment to quality and performance is evident in every detail of the Dia-Sharp. Proudly made in the USA, it reflects decades of sharpening innovation trusted by craftsmen, chefs, and tradespeople around the world. If you demand speed, consistency, and portability in your sharpening routine, this fine diamond stone delivers.
