Natsuyato from Iwate Pref, where north coast of Japan. Approx. grit is #800-, for the middle process of knives, tools. Wide range and easy to use. As well as other mines, Natsuya-to is not mined any more. Water absorption is very quick, Rich & impressive slurry comes out easily, Particularly good for carbon steel knives. There was a crack in the part of side to the bottom, but it stopped in the middle. We sealed the sides and the bottoms by Cashew 3times. Please note that these are not for beginner sharpeners since they're harder to use. These are natural stones meaning that every single one of them is different so my measured sizes are not accurate. This is a lifetime investment for people who live sharpening their razors and tools, do not hesitate to ask me your questions
