I realize that the JNat slurry stones are flakes and the Coticule cuts with garnets in the slurry. But, where would the Coticule fit in an Asano Nagura progression? From my magnification analysis the general results of my Tomo Nagura and my Coticule are similar although the Tomo gives me a more refined edge on my Shuobudani. The Coticule slurry seems to cut faster. Does anyone think the Coticule slurry is incompatible with a JNat? Am I committing sacrilege?
