suggestion for best keychain/bottle opener/tool?

[asofel]

Money clips have been talked about commonly here, and thanks to the recommendation for the beza money clip (thanks alobar i think?) i am a new man.

So OOT, anyone have any suggestions on a keychain that has a good bottle opener? I'm open to ideas on things that are like mini leathermans, small swiss army gadgets, etc etc.

Something like this might be cool:



Similar idea, but I don't think the tag style is all that great. Seems kind of poser-ish:



Something like this might be better:




Maybe just a small swiss army knife:




Basically, I'm just tired of embarassing the other guys in the office by flicking the bottle caps off with my thumb, so I need something to help me blend in better.

Any thoughts or tips?
