I have stoned a slight radius on the outer points of hand sharpened drills and made them actually cut undersize!
For twenty years, I wore an eye-loupe clipped on to my egeglass frame, as everyone would constantly ask me to sharpen their tools! Having a nice set of diamond plated files, and assorted stones in my toolbox, was a necessity in the places I'v worked!
The hardest thing to sharpen is those damn one lip carbide engraving tools, as one slip and the point is toast!
