The Pry.Me Bottle Opener holds tens of thousands of times its own weight, and you can pick one up now from the Boing Boing Store.
This remarkable keychain is considerably smaller than any of your keys, but don't let that fool you: it can easily open any bottle, and could even tow a trailer full of bowling balls if you had a hitch small enough. It's made from Grade 5 titanium — the same type that's used in countless industrial and aerospace applications. Needless to say, this tiny piece of hardware will easily outlast you.
Because of its unique shape and comically high tensile strength, this bottle opener can be so small that you'll never notice it's in your pocket. It also includes a heavy-duty key ring to replace the flimsy one that probably came with with your house keys. You can get one of them here for $10.99.
