I've been meaning to try diamond paste on my hard black arkansas stone. It gets a razor sharp edge on its own, I'm talking woodworking sharp, I've never tried to shave with a straight razor honed on it. But I've had such good results with Nortons that I stopped using my arkansas stones all together. When I picked up straight razor honing, I just went straight to my Norton stones. But I keep meaning to get some diamond paste and use it on the arkansas stone. I know of some master woodworkers who use that method to get an ultimate edge on a chisel. Has anyone compared the edge gotten on finishing a razor with diamond paste on a hard arkansas stone versus CrOx on a strop?
