Well it is worth noting that the Nortons, Shaptons and Naniwa super stones and Choseras are not made for razors. They were made primarily for sharpening tools such as plane blades and chisels. The Japanese especially are enthusiastic about sharpening their wood working tools. Any of the fore mentioned do a stellar job on razors .... in skilled hands.

I would do a search on google and on Knife Forums and see if anyone has reviewed results with that hone. You could also do a search on amazon and if anyone is selling it through them there may be reviews.
