Jim Koepke's #8000 Norton water stone uses 3 um abrasive particles
This is interesting and agrees with the specifications in the (current) Norton 2015 catalog:

What is strange is a chart from 2007 puts the Norton 8000 water stone at 1.2µ particle size.
The question is was the 2007 chart in error or has Norton changed their stone? (error more likely?)
There is lust in my heart for a finer stone, just because. There are also moths in my wallet when it comes to spending that kind of money for an increase in sharpness that would be hard to justify since my edges can perform quite well with my current sharpening equipment. Maybe if an urge to get my straight razor in shaving shape came over me, one of these would be advantageous. How can that be explained to SWMBO in such a way as she will be the one to suggest it is worth the money?
