I appreciate your feedback gentlemen! Really surprised of your opinions on the C12k, though! The Naniwa 12k is one of those things that seem ridiculously priced priced to me. About 170$ cad for grit in a block.. though currently on sale at paul's finest. I have the feeling I would get a hell of a buyer's remorse if I pulled the trigger on that. What did our ancestors use? I'm sure the common man didn't have expensive stones like that, or did they?
