Over the years when I had bought sets of drills, the balance of the set (once a few were broken or lost or borrowed by others) - ended up in a cigar box. And a new set was then utilized. Also was given some other folks drill collections in a box.
To help with using what I have, I got a drill cabinet and sorted all those drill bits into the proper location in the cabinet. The cabinet is a very nice setup what with the individual bins.
If I sharpen a bit with the sharpener, I use a marker on the ground tip to check on the progress and when it is done, I then mark the sharpened end.
