Koppa stones from Kyoto

The fine grit natural stones

water stones

Koppa means small pieces. If you want to start natural stones for your kitchen knives, they are good for trial. You can use them for razor or chisels too. They are from Kyoto.
I have some other stones. Please let me know if you are looking for something. They are super fine grain stones.
