Thanks. Since the blade is already satin, I figured maybe start with the 400 and go up from there, but I thought I'd ask, having never done this particular thing to a knife before! It's not like there's a bunch of roughness I have to take out of it.

Well... there's a few minor scratches I managed to put on the blade, since all of my knives are users (I'm carrying it right now as a matter of fact) which is what spawned this idea in the first place.
