Id be interested if there was a website that identified Jnats. I know it would still be someones opinion but if some of the masters have done this it could be helpful. Anyone know of any?

Guessing here but I think my shobu 100 i bought 3 or 4 years ago is an Asagi. Although its just a gray in color. Its hard, but not as hard as other Asagi stones.

This identifying website would need to be broke down in mines too.
