Let me ask this: For those of you who have the Zulu Grey, does it give a smoother edge/shave over the Naniwa SS 12k finishing stone? Say polishing on the 12k then move to the Zulu, does this give you a better shave that is worth the money for the Zulu?
I'm looking into buying one in the 8x3 size if there is much improvement from the SS 12k.
