I don't know if you folks would know about these. Many of my violin maker friends use them on small tools:

I bought another version of it almost 30 years ago, and at the time there was also an 8000 grit stone available for it, which I have.
I tried it on a new-old Ebay razor today, and it worked great! You don't want to know how fast it set a bevel! One wouldn't want to use the 1000 grit stone it comes with on a razor--it's much too fast--but the 6000 that's currently available might be nice for someone doing a lot of work.
