Stab yourself once while rummaging around and you never do that again. Stab yourself under the fingernail while rummaging around and you might burn a whole building down.

If you do any kind of precision work (e.g. electronics, glasses, changing the battery on a kid's toy, etc) I strongly encourage getting a proper precision driver and bit set. I like ifixit but there are knockoffs that come from literally the same factories for a lot cheaper. Those tend to come with a bit that is literally a sim ejector pin AND a box that keeps everything organized and together.
