Designed for heavy material removal, it handles everything from large knives to fine tools without oil—just water or dry use. Durable and efficient, it’s the go-to choice for professionals and enthusiasts seeking rapid edge restoration and long-lasting performance. ## Description From the manufacturer The DMT Difference Diamond Uniformity, Coverage, Surface Flatness DMT uses micronised monocrystalline diamonds, precisely sized for a more uniform diamond surface. No other diamond sharpeners offers micronised monocrystalline diamond and most offer the lesser grade poly-crystalline diamond. Mono-crystalline is like an ice cube made up of one particle holding its form while poly-crystalline is like a snow-cone made up of many small particles that get sheared off during use. Coverage: DMT’s process assures the most diamonds per square inch in the industry providing a more durable sharpening surface. Surface Flatness: DMT bench stones are engineered flat, assuring even contact with the knife or tool. Choice of Diamond Surfaces Interrupted or polka dot surface for which DMT is famous has slightly recessed holes that will collect metal fines (swarf) removed during sharpening to prevent loading. Fast sharpening action; not recommended for pointed or very small tools. Continuous surface presents a more conventional looking sharpening surface. Fast sharpening action; able to use on small surface edges. HardCoat, DMT’s newest proprietary surface, is able to withstand the rigours of ceramic sharpening, providing an even longer service life to the sharpener. DMT Commitment DMT is committed to providing the best diamond sharpeners in the marketplace. If the sharpener is found to be defective, we will replace it.

Guided Sharpeners If you are unsure about sharpening, try one of DMT’s sharpening systems to assist with proper sharpening angles. All systems revolve around the 7-angle adjustable blade guide utilising either 4-inch diamond whetstones in the Aligner models or Double Sided Diafold Sharpeners in the MagnaGuide line. The blade guide can also be used with DMT’s bench stones. About Sharpening with DMT Care and Use of DMT Diamond Sharpeners All models are designed to be used dry or with water so there are no messy oils and extensive clean up to worry about. Always clean the DMT sharpening surface after sharpening. Rinse surface with water and wipe dry. After several sharpenings, clean more thoroughly with a mild abrasive and brush; rinse surface with water and wipe dry. Always put away dry and store in a dry environment. Use leafing (paper towels, cloth, plastic storage bag) in between your bench stones to prevent abrasive sides from rubbing. Use Dry or with Water Clean and Wipe Dry Store Dry Get the Most out of your DMT Sharpener There is a ‘break-in’ period for your diamond stone. Initially, it will feel especially rough but will smooth over time without impacting performance. Let the diamonds do the work; just light strokes with the edge to sharpen, same number of strokes each side. Approximately 5 or 6 strokes per side (depending upon condition of edge) compared to 30 strokes per side on a conventional stone, saving time and extending the life of the knife or tool. Start with a coarser grit for damaged or dull edges and work to finer grits. The work the edge is to do will help you determine the grit needed: Rough work, end with coarse grit (cutting cardboard); finer work, work through finer grits (food preparation).
