Sorry Rick, but what is your logic here? If the bevel is already set then what purpose does spending more time on the 1K do?
In my opinion all this will do is waste good metal.
Good point...and I wondered about that after I'd written it.
My logic is if he's spending time on the 5k and not sure when they're done, along with having a couple of razors that weren't quite there after spending time here and moving as, as in the original post, I would guess the bevel needs more work. It may just be a quick touch up, it may need to be reset. Perhaps it's set and needs just a little more umph. If the 1k is where most of the edge comes from, to me, this makes some sense. Get it right there first.
Even if a razor was shaving well initially, now it is not. Doing 10-12 strokes on this stone may help to reshape things just enough and isn't going to waste away enough metal to worry with.
