To add to Robert Sorby’s distinguished repertoire of sharpening tools we’ve introduced two handy sized diamond sharpening stones. These solidly formed sharpeners can accommodate a variety of materials and will easily sharpen high speed steel and tungsten carbide. No need to throw away your dull TurnMaster tungsten carbide cutters.

Available in two sizes and in two grits (600 and 1000), the larger credit card stone is coated both sides while the smaller version is single sided with a plastic backing. Slim Diamond Plate - 25mm wide x 75mm long x 1.5mm. Available in 600 (WDS 600) and 1000 (WDS1000) grits. Double Sided Diamond Plate - 55mm x 85mm x 1.5mm.
