The DMT W6FP is a 6-inch Fine diamond whetstone with case with the brand’s signature monocrystalline diamond surface bonded to a precision-flat steel substrate. The diamond grit cuts faster than traditional sharpening stones, stays flat over decades of use without dishing, and works dry, with water, or with mineral oil depending on preference.
Use it on kitchen knives, hunting knives, pocket knives, woodworking tools, lawn mower blades, garden shears, fish hooks, and any blade that needs precision sharpening. The flat diamond surface produces a true edge geometry that lasts longer than edges put on softer stones.
DMT (Diamond Machining Technology) has been manufacturing diamond sharpening tools in Marlborough, Massachusetts since 1976. Every DMT stone is American-made and carries the brand’s reputation for the longest-lasting flat sharpening surface on the market.
