I wanted to share a nifty idea I had these days. Maybe it is not new at all. I searched for keychain devices that take up screw bits. There are some, but they either do not hold them well or are a more expensive item like the thing from CRKT. I ended up taking a bit holder extender and had a buddy with a standing drill put a 3mm hole in the socket end ( where it goes into the handle of your driver ). I put a split ring through and now I can have it hanging from my keychain. A bitset from Aliexpress with rubber holder goes in the EDC pouch and you´re set up the cheap way. Of course you do not have much torque, but it serves it´s purpose.
