Thread: New Shapton high carbon stones

Those came out a few years ago. There was info on So Yamashita's site and on the Shapton USA site. IIRC they are gray and where the white glass stones are for one tool steel the gray are for the other. Referring to the Japanese "white" steel and "blue" steel IIRC. Lynn told me they are good and about the same as the other glass stones IIRC. Harellson Stanley is the distributor for Shapton in the USA. He participates in the woodworking forum and you can probably find out about them there.
