Small drills for Machining or Jewellery use are sometimes sharpened with 
what they call a Wish Bone Sharpener.  This is a low tech device with 
wheels that rubs along a grindstone, diamond plate, or sheet of fine 
sandpaper.  WHile low tech it does work well on drills - I've used it on 
a couple of carbide drills.

There was an article online at the address below or I can send info if 
anyone wishes it including photos & instructions from a commercial unit 
like shown in the beginning of the article.   I actually have the 
complete article saved as a file too that I can link to in someone wants it.
