I was expecting a little bit of dullness or even a scratch or two.
But the surface is just dense and clean.
The surface is so smooth I was wondering if this ainīt a bit too much.
The stones of course work at their best afterwards!

I was wondering how this is possible.
Even 1.500 grit Sandpaper or a 1.000 Waterstone donīt leave stones this bright.
I wonder if the 325 would leave a nice finish too at a reasonable sucction rate.
I compared the DMT to my Sandpaper and obviuosly this was a mistake,
because 325 sandpaper leaves my stones very scratched...
The DMT 325 = 45 micron particle but how much of that particle is embedded in the nickel matrix ? The 325 paper is likely even a different grit system (larger) & the whole particle gets rubbed around. The Atoma 1200 plates are a different animal again. The raised regular spaced pimples on the plate reduce stiction drastically but the DMT 325 leaves a much finer finish.
An Atoma 400 plate will destroy any razor edge you put it to yet the particle size is a bit finer than the 325 DMT. As always in this sport. So many variables
