Or even a file.

I guess you can file drill rod. I'm not sure you could file a good
screwdriver, though. And poor screwdrivers, in my opinion, are not worth
having.

The best quality jewellers screwdrivers can be filed! You don't want a blade
that is very hard, just tough. they should be sharpened by filing cross
wise, as the tool marks help the blade "grip" the slot.
