Thread: Help with Naniwa set up

Karl, going by the JIS grit chart I notice that the micron size is close in the lower grits. So a 1k USA hone is roughly equivalent to the same grit in the Japanese hone. Above that you start to see a difference in micron size between the designated grits labeled on the hones.

So with my finding the Norton 4/8 an effective combination I have found the 3k and 5k in the Japanese hones roughly equivalent. For my preferences a 1k,3k,and 5k would be all I would need. If I wanted finer polishing an 8k and more icing on the cake a 12k would top it off.

These are my preliminary impressions based on the information from the grit chart. What little honing and shave testing I've done with this setup seems to bear it out and if I read him right Rayman has had the same conclusions and the same results.
