Spot on! About the same way certain grit sizes are attributed on SRP to Eschers, coticules and barber hones. We use the stone a couple of times and guesstimate

I realised my first DMT attempt today had fractured the blade edge. Maybe a foil edge.
So I dragged it on the corner of the stone.
Got out my worn Atoma 1200 . I figured it was useless because its worn in the middle.

Raising a slurry I realised that the lighter blue/grey part of my wacky Naky produces white slurry. The darker blue/black part produces dark brown slurry.
The dark slurry takes over the white when they mix.

Anyway I did 4 dilutions and it appears to be a killer edge but I wont know until I shave in a few days.
I hope the edge works well



Edit:What would happen if I used a diamond plate on a diamond plate? Would the world end?
