I used wet stone at the beginning and quickly ruined both side. Since I did not how to flatten the stone back that was the end of it.
I moved to the sandpaper method and that worked pretty good. I passed the “arm shave” test successfully.
Then I saw the worksharp 3000 and bought one. I used it few times. It works fine but
In all honesty I would done just fine with the sandpaper.

Now when my chisel gets dull I reach for a 400 grit and take a few lap and it’s useable again.
For what I do with it, this plenty fine.
