wow old thread, good topic though. in trying to figure out how to sharpen very small drills, for those not familiar with it, remember that the traditional or at least common geometry on the end of the drill, where the clearance is sort of 'rolled' on is not the only way to sharpen a drill. Faceted sharpening is as good or better imo this where a primary and second clearances are ground on as flats - here's a pic of some i did

for small drills a hand held jig dragged across some fine emery cloth can be used to put a faceted point on - no grinding involved. Guy Lautard in one of his bedside readers describes how to make one.
