1/2" and larger, suggest checking Fine Woodworking and other wood references 
at local library, as well as Machinist references for metal drilling.

Several problems arise with hand sharpening, angle of cutting edge, shape of 
flute behind cutting edge, angle of face of cutting edge, and as Joe Dillet 
mentioned,keep these the same on both sides of a twist drill. Best to get 
some old bits and grind them up practicing.

My best drill bit purchase was a $2 garage sale sharpening jig for use with 
a bench grinder.

A Dremel type tool with small cylindrical stone works well for touch up on 
twist drills and Forstener type bits.

Drill bits we buy are general purpose using same specifications for all 
sizes.  Ferrous metal, non-ferrous metal, wood, and plastic each take 
different grinds for best results. Old Joe
