The Shapton Pro 15000 Kuromaku is the highest grit in the Pro line and one of the finest ceramic whetstones available - an ultra-fine finishing stone for sharpeners who want a true mirror polish and the absolute maximum from a knife edge. Single-bevel Japanese knives, traditional straight razors, and specialty carbon steel knives with hardness above 63 HRC are where this stone earns its place. The same hard ceramic bond that defines the Pro series is present here - consistent, fast-cutting for the grit, resistant to dishing, and ready with a splash of water. Black color-coded. We are a registered Shapton distributor with full warranty support.
At 15000 grit the refinement is beyond what most kitchen cutting tasks require - this is a stone for sharpeners who treat edge finishing as a craft in its own right. The edge it produces is objectively sharper on harder steels and on single-bevel knives like yanagibas, debas, and usubas where the geometry demands a near-perfect flat back, the 15000 is the tool that makes it possible. Use it at the end of a full Shapton Pro progression after the 8000, with a leather strop as the final step before the knife returns to service.
Care Instructions: No soaking required - splash with water and use immediately. Rinse carefully after each session to prevent slurry buildup. Allow to dry fully before storing. Flatten with a fine diamond plate to maintain surface trueness - at this grit, even slight dishing affects results noticeably. Store completely separated from all coarser stones.

Very nice stone. It's about half as thick as my Chosera stones, but very nice nonetheless. The stone is nice and hard and pulls metal instantly. The splash-and-go non-soaking quality is great. This 15K might not be as legendary as the Chosera 10K, but its a fraction of the price and a great finishing block for sure. I have a combo of Chosera and and Sharpton Pros. 400, 800, 1000, 3000, 5000 are Chosera and the 220, 8000 and 15000 are Sharpton. I'd highly recommend either brand, but do prefer the feel of the Chosera. If you are looking north of 5K then these Pros are your best bet!Note: Although I do used these on kitchen blades, I used them primarily to reprofile and recondition my outdoor scandi and convex ground knives.
