Work up a little slurry with a diamond plate to set the bevel, with circles and X laps. Then wash the stone and razor, joint the edge lightly and reset the bevel on just water and a clean stone.
A little slurry will make the stone more aggressive but, will damage the edge, with the slurry pounding it.
Once the bevels are flat, you can bring the edges back to meeting quickly on a clean stone.
May take a few laps and a little pressure depending on the condition of the bevel and edge.
You will be surprised how aggressive that stone can be. A lap or two can pump up a failing edge. Too many laps and the edge is sharp, but harsh.
Experiment, with a 20k stone, what's the worst that can happen?
I think you wrote that as I was doing it. I was pretty close to doing what you said.
Here is how it turned out:
Just kidding. The razor arrived unsharpened and I also killed the edge so that I wouldn’t cut myself when I was cleaning up the corrosion. This pic is right before I started the session and it was very dull.
