I have heard somewhere the suggestion that after the 12K hone, whether Chinese or Naniwa, that the coticule will still make for a smoother edge. On the other hand, I hear the typical coticule said to be approximately comparable to an 8K-10K stone.

So...is there a case for going from a 12K finishing stone to the coticule?

Gentlemen, your arguments and experiences pro and con please!
