Designed for those who demand the highest level of edge refinement, the Naniwa Chosera Pro 10,000 sharpening stone is a true finishing stone for serious knife enthusiasts and straight razor users. At this level, the focus shifts from shaping the edge to perfecting it—delivering exceptional smoothness, keenness, and cutting precision.
Despite its ultra-fine grit rating, this sharpening stone remains efficient and controlled in use. Its hard, dense construction allows it to cut cleanly while wearing very slowly, helping maintain a flat, consistent surface over time. This stability is especially valuable during final honing, where precision and feedback are critical. The result is a highly refined edge that excels at push cutting, fine slicing, and razor work.
Like all stones in the Chosera Pro series, the 10,000 grit sharpening stone is splash-and-go, requiring only light surface wetting. Extended soaking is not recommended due to the resin-bonded composition, which is designed for surface use only.
Stone Size: 210mm x 70mm (8 1/4" x 2 3/4")
Weight: 1.5 lb (686 g)
Care Instructions: Splash-and-go use only. Do not soak. Rinse after use and allow to air dry completely before storing.
Customer Feedback Summary: Customers consistently describe this sharpening stone as one of the finest finishing stones available, noting its combination of hardness, smooth feel, and excellent polishing ability. Many highlight its fast cutting speed for such a high grit, along with minimal dishing and long lifespan. Users report achieving extremely sharp, highly polished edges comparable to much more expensive natural stones. Overall, it’s regarded as a top-tier sharpening stone that delivers outstanding results for both knives and razors.
Please note: Naniwa has updated the name of this stone from the Chosera 10,000 to the Naniwa Chosera Pro 10,000 (sometimes spelled Chocera). The stone itself remains unchanged.

It is a very hard stone yet it polishes it is thicker than a standard Chosera probable 15% since it is an occasional stone unless it is used to sharpen razors daily it is likely to last many years .Dishing is minimal since the stone is so hard many high grit stones are soft it also means that you can work quickly on it without fear of cutting into it .Well worth the money especially from CKTG.
