Thank you for viewing. I am introducing a natural whetstone from Kyoto Shobonzan. This is a Tomae Iromono, with a moderate hardness that makes it easy to sharpen with. It has no noticeable streaks, and is a high-quality whetstone, 40-cut. The size is 203mm x 83mm x 25mm, and it weighs 1005g. Thank you for your consideration. ※ I received this directly from a quarry operator in Kyoto. Please be aware of accounts selling stolen goods by foreigners.
