Japanese natural whetstones have become rare and highly sought after. The stones we carry have been mined in the area around Kyoto, Japan and have been sourced for us by Mastersmith Shosui Takeda. Each stone is unique and will vary in appearance. As a natural material, it is not possible to measure the precise grit of each stone, but we list an approximation.
#8000 grit whetstones and higher are used for the last steps in polishing and creating a mirror finish. 8000 is also what many consider needed for vegetable cutting.
Ohira - 10,000 grit
Hideriyama - 8,000 grit
