DMT, who pioneered diamond sharpening technology, uses uniform and precisely sized Monocrystalline Diamonds which are permanently bonded to nickel on a precision ground plate. Unlike lower quality polycrystalline diamonds used in competing products that break apart and wear away easily with use.
DMT Diamond Whetstones, when used with reasonable care, will give you many years of service.

DMT sharpening products have two advantages over waterstones and oil stones. They cut more quickly and stay flat, but additional honing with finer abrasives is needed for the best edge. An 8000 grit waterstone is an excellent choice for final honing after the an Extra Fine (1000-1200 grit) diamond plate.
