For sharpening knives with blades made of ceramic or powder-metallurgical steels, HSS tools as well as tungsten carbide machine tools. Diamond stone with two opposite plates of different grits. The stress-free sandwich construction guarantees flatness. Including mount.

DMT Diamond Stones

The American manufacturer Diamond Machining Technology (DMT) is the founder of interrupted surface technology for diamond sharpening stones, and has been the market leader for diamond-coated sharpening equipment for years. The high-quality sharpening tools are manufactured at the company's headquarters in Massachusetts (USA).

Monocrystalline* diamond particles guarantee a long service life and excellent material removal
Uniform grit sizes and a dense diamond distribution for even grinding patterns
Round recesses prevent clogging due to grinding debris
Permanently flat and warp-free thanks to supporting plates made of steel or warp-free plastic with a nickel matrix
Colour coding of various grit sizes
100 % made in the USA

DMT Hardcoat Surface

The HC surface offers extremely tough and wear-resistant diamond surfaces and therefore considerably elongates the service life of sharpening stones, especially when sharpening very hard cutting materials.

Monocrystalline* diamond-coated sharpening devices:

Diamond-coated sharpening devices remain permanently flat, and are especially suitable for tools with straight blades, as well as for producing flat surfaces (e.g. backs of plane and chisel blades, plane soles, scrapers). Also suitable for carbide coated cutters, tool steels, HSS and non-metal materials (glass, ceramic, etc.). We recommend moistening diamond-coated sharpening devices with water or lapping fluid and grinding with little pressure.

* Monocrystalline diamonds are significantly more wear resistant than the polycrystalline diamonds used to make lesser quality diamond sharpening tools.
