Katahiro Kubota Water Grinding Stone

Professional sharpening stone from Katahiro Kubota. The combination stone is specially designed for resharpening fine kitchen knives. The combination of 1000 grit (fine grinding) and 3000 grit (polishing) achieves exceptional sharpness of your knives.

Instructions: Soak the whetstone in water for 10 minutes before use. The rubber base gives a secure hold on the table/shelf. Use the 1000 grit to give the knife a fine grind. To get a perfect grind, professionals polish the edge afterward with the 3000 grit for the so-called high-end polish. With a non-slip rubber base.
