while looking for a link to the honing stone I have been using for decades, I stumbled on a quite interesting research about difference in the wear on the instrument, when different sharpening materials are used. They used Ceramic and Diamond stones of the same grit.

I mentioned on another thread that M4 came out well, I was wrong it was M3 although I kind of expect M4 to fare slightly better if they tested it.
