Well as far as grind goes it is about a 3/4 hollow grind. I bought my stones used so I do not know the exact grit but aprox 400-1000-4000-6000-8000 and I use them in that order. I have even gone back to a coarse grit with this razor of about 200 grit. It is not that. I have sharpened many razors with no problem. Also there is no discoloration. It was a little rusty when I got it and without scales but not on the edge, Most all of the rust was in the center of the grind where the logo is. Again, I have no way of knowing the exact grit of the stones but I am pretty good at guessing that since I have about 15 plus about a dozen small ones that are about 1 x 3 that I don't use for razors.
