I don't buy "gunsmith" screwdrivers. I have bought a bunch of old drivers at country auctions. I grind or file these to fit as needed. Every screw, every time. There are no shortcuts to do it right. I have so many that sometimes they are ok with little to no work.

I don't like drivers with multiple bits. I can always feel a little play in the bits. The older quality screwdrivers seem to be made of tough steel. I have never broken one.
