My library has a lendable “Ultimate Screwdriver Kit” that has every bit size and type I’ve ever heard of, security Torx, pentalobe, oval, gamebit, spanner, etc etc. Also a bunch of different styles of bit holder, and a bunch of attachments like angle adapters, depth setters, torque limiters, etc. Only tangentially relevant I guess… but if you run into a problem like this again, check your local library to potentially avoid having to buy obscure bits online!
