I don't know enough to provide the data and I don't know that I've seen this anywhere else on this site. Seems it would be useful information for a guide that has a list of Steels and the optimum grit to stop at when sharpening. Realizing some of it may be use dependent. I've read S30V likes a toothy edge. 600 Max? 400 Max? Which steels are best served by a mirror polished edge? Post your experience and I can try to capture it when there is a consensus, if that is possible.
