Zwilling J.A. Henckels® Twin Stone Pro Sharpening Stone

Professional precision-edge maintenance for your knives, this is the traditional Japanese method for shaping and finishing blades to razor-sharp edges. The 250 grit is for rough grinding, to return edges to their original shape. The 1000 grit is for fine finishing, smoothing and polishing cutting edges. Double-sided stone requires no pre-soaking. Made in Japan.These softer Japanese stones have several advantages over harder stones. Because they are softer, they do not become glazed or loaded with detritus. Plus, they are lubricated effectively with water rather than oil, which can ruin the stone. In addition, with these stones the worn material and the water form a slurry, which in conjunction with the stone, sharpens and polishes the blade.
