There's a key on the cover-page of that site that's been turned into a bottle-opener. Two men, each with a key, each turned simultaniously ... End of the world. Rather chilling.
The best one in my opinion is the Atwood G5 Roid Prybaby. The cap comes off easy with hardly a dent in it!
Used to use this when I worked in a bar. Attached the retractable clip to belt loop. Worked great first time every time and when I let go, would zip back to hip
I find that the only thing Leathermans can't do well is open bottles. Sure, they CAN, but the bottle openers on the full sized tools and micra usually take 2 tries and mangle the cap. My go to is a Star Opener mounted to the wall. Oh wait, we're talking about keychain tools... The PockettoolX (I guess Leatherman bought them recently?) Brewzer works pretty well but it's rather small and hard to get leverage. The Piranha is my go to EDC opener. Gets a nice solid grip, good leverage, gets the job done. Next on the list is an Attwood of some sort.
