This is a natural sharpening stone (awasedo) from Shobonzan in Umegahata, Kyoto. Shobonzan awasedo has been highly regarded since ancient times as the highest-grade finishing stone. Its fine grit and stable sharpening feel bring an extremely beautiful finish to the blade's edge. With its moderate hardness and the way the abrasive mud spreads, it allows for a gentle touch on the blade while still achieving a sharp cutting edge. It can be used for a wide range of finishes, from kasumi (haze) to mirror finishes, and is ideal for the final finishing of razors, high-end Japanese knives, and planers.
