Thank you for viewing. Kyoto Shobonzan Natural Whetstone Awasedo (Finishing Stone) Asagi (Color/Type) Mizu-Asagi (Water Asagi) This is not a hard, "kachikachi" (very hard) Asagi. Despite its hardness, it has good abrasive power and a smooth polishing feel. I wouldn't mind keeping such a high-quality natural whetstone, but I hope someone with the same hobby can use it. Although I cannot definitively say that the natural whetstone for sale is from Kyoto Shobonzan Nakayama, it has almost the same polishing feel, hardness, and smooth polishing feel as the Awasedo, Asagi, and Mizu-Asagi I have from Nakayama. It is an expensive item, but... Please consider it if you are interested.
