DMT Diamond Sharpening Stones

DMT has been making diamond sharpening stones in Marlborough, Massachusetts since 1976, and they're the company that put diamond plates on the woodworking map. Industrial diamonds bonded to a flat steel base means a stone that cuts fast, never dishes, and handles hard Japanese steels and modern alloys without complaint. No soaking, no flattening, no fuss.

Coarse to extra-fine grits for chisels and plane irons, the Dia-Flat for keeping your waterstones true, and the Diamond Wave for getting an edge on curved gouges and the inside of carving tools. American-made and built to outlast just about any other sharpening kit on the bench.
