Original description:
This bit driver can carry five standard bits. One at the tip and four more inside. With a handy clip and a length of 145mm it fits in most of your pockets.
Remix:
- added a more “aggresive” knurling that allows more grip
- used a differend bottom part from mini bit driver keychain (also has more “aggresive” knurling)
