Thread: What is the highest grit you have used on a stone?

I think I am around DMT 425

Folk that tape might also consider that the
steel of the spine is part of this process. The
a'retentative folk might use that old razor with
a lot of hone wear for a half dozen strokes to
condition the hone surface. The old razor may become
your fav' shaver in the process. To one degree
or another this initial slurry interaction takes
place on any hone and with many a nagura/ rubbing
stone.

In my opinion, circles and Japanese strokes that
we see in video by the better hone masters when a razor
first touches the next hone optimize this process

Over time a DMT will calm down and this is less
an issue. You want a DMT that is coarse enough
to be durable and aggressive enough to remove
that half a sheet of paper bit of hone that is
needed to keep the hone flat enough over time.
The slurry is a key byproduct...

I just finished this as seen in this thread( Chinese 12k dressing stone) and it works quit well. I believe it just may take away that first razor smoothing effect or take the place of. It definitely smooths out the roughness left from the DMT.
