A bit more testing with the mystery Mikawa. I was able to take the #2 to Tomo and get an edge so I tried the same progression with the #4. The stones were already numbered when I got the lot. At each stage I stopped 40 on linen and 20 on leather. The #4 is less pure than the #2. It was grey flecks and looks gritty. But looks can be deceiving.
The #4 slurry killed the edge completely. The Kita Nugara slurry brought it back slightly. Pure water laps brought it back all the way. There doesn’t seem to be much in it between the #4 and #2. Both seem to be pre-Tomo level.
