That would have been my plan. However, the last razor I hand-sanded, I developed incipient tendonitis. That was nearly a week ago, and still I have to be careful using that arm and hand.
Come to think of it, it was precisely that FBU that brought on the tendonitis. I didn't touch it with the Dremel. I went at it with wet and dry, 220, 320, and 400. I left it at that point for working on later, and woke up with a sore arm.

Not to worry. I'll treat it like antique Chinese porcelain.

The other razors in this lot I did touch on with the flap wheel. It didn't hurt them. They were all of them needing more work than the FBU.
