Hey just started honing my own razors and right now I am getting a decent edge from my Naniwa 4k/8k stone especially after I finish with CrO paste. However it is still grabbing and not as smooth as I know it can be. I think I want to buy another stone but with finances as they are I can only get one good stone. Right now I am looking at either 1) Zulu Grey stone from South Africa or 2) a 12k or 16k synthetic hone. Any suggestions?
