The idea that using a diamond plate to raise a light slurry will quickly wear out a stone, well I know that over time it would, yes. I have flattened literally 100s of stones with the Atoma 400 plate, and I am a stronger man for it, and I am using as fresh a plate as I have, bearing down with my full body weight under running water. It is such a chore that I have to take breaks and even walk away from it for a few minutes. It takes so much time and effort to just lap out a 0.05mm divot, I cannot see myself actually wearing out a 20mm thick hard awasedo razor hone in a lifetime of normal slurry raising. Softer stones, yes, they do wear out faster and under an Atoma you can get that divot out in maybe 2/3rds the time, but really hard stones like razor users have, it would be a slow process to deminish a stone.

Even the 140 grit Atoma can be a bit slow on certain stones. I find 40 -80 grit SiC powder on glass speeds things up considerably until the diamond plates can come into play.

Thank you all for your suggestions, I try it after a very fast coticule, a deep rock, I raise slurry on coticule and dilute about half way. After I finish on Okudo , 100 laps, is a small stone, the edge is improving considerably over the coticule on water. The shaving is absolutely fantastic, I don't even need 2 passes. For now, this is my favorite finisher, beter than my Hohenzollern. I will post more of my experience, as i will try it with slurry.
