DMT Diamond Sharpening Stones, Bench Stones & Lapping Plates
DMT (Diamond Machining Technology) sharpeners use industrial-grade monocrystalline diamonds bonded directly to a steel substrate. Unlike oil stones or waterstones, DMT stones never dish, so every stroke removes metal consistently from the first pass to the last. Whether you need a quick touch-up in the shop or a full re-grind from scratch, DMT offers the right grit and format.
Formats for Every Sharpening Task
The DMT 10" Dual Grit Diamond Sharpening Stones combine two grits in one bench stone for fast progression, while the DMT DuoSharp DuoBase holder keeps the stone stable on any bench. For pocket or job-site use, the DMT Diafold Dual Grit compact sharpener folds flat and slips into an apron pocket. The credit-card-sized DMT DiaSharp Credit Card Sharpener is ideal for touching up chisels between cuts.
Diamond Paste & Flat Lapping
When mirror-polished edges are the goal, the DMT 3 Pc Diamond Paste Kit (6/3/1 micron) delivers a progression from honing to stropping on any flat substrate. The DMT 95-Micron 10"×4" DIA-FLAT Flattening Plate quickly resurfaces waterstone faces or flattens chisels and plane irons in one step. All DMT products are backed by our quality guarantee.
