Thread: Natural Stone Grit Confusion

This question is mostly for the people who actualy are able to estimate the grit of their naturals and in particular apanese stones. From my very limited experience in with my Nakayama, I would have a difficult time giving an estimate of it's grit and I know some people are able to estimate. When you estimate, are you giving an average of how it is cutting freshly lapped?
I start out with a slurry cut in with a DMT. At that point, the grit has to be pretty low, as it is cutting very fast, but not so low as to leave deep scratches. Maybe a fast cutting 5000? Then moving to water I hone and eventually gradually lightening pressure and finish up to where I can shave. Since it produces a uniform haze finish, I would not even begin to know how to estimate the final grit especially being "raised" on synthetic hones where you can literally see bigger scratches for 1200 than 8000 etc.
