Professional Super-Fine Whetstone Engineered for Precision Edge Polishing
The Naniwa Chosera 10,000 Grit Sharpening Stone is designed for the final refining and polishing stages of professional knife maintenance. Its ultra-fine corundum abrasive surface helps remove minor edge imperfections, refine an established bevel, and produce a smooth, highly finished cutting edge on kitchen knives and other compatible blades.
