DoohicKey Keychain Multitool
One-piece multitool
Got it over 6 months ago and it has been attached to my keyring ever since. It is almost invisible and barely noticeable, until you need it. The wide screwdriver tip, the bottle opener and the box cutter are perfect additions to my Leatherman Style PS Multitool, which also comes with me everywhere, including planes, as they are both TSA clean. The DoohicKey also comes with a wrench and a ruler.
