I have a screwdriver bit set that just includes one of those, very tightly secured. Whoever was responsible for ensuring this was neccessary: You are a hero.
I don’t know what in the hell I did, I have one of the solid circular round ones with a small hole in the back for the keychain. It’s been on my keys for ages. One morning I went to put my seat belt on and got a sharp stab. I pulled my keys out and it was bent 90° and I just the tiniest little bit of blood on it.
