As a cyclist and a drinker of fine craft beers I can't see much fault with these bottle-opening bike seat clamps. If they make it out of Kickstarter and you procure one, please enjoy responsibly.
Asking price for Kickstarter funders is $US20 for the bare-bones clamp and $US30 for the quick-release (saves $US5 each, respectively). Both boast a bottle opener and a variety of colours and this second time around the project is on track and about 70% funded (an older, less savvy version didn't make it through the first round).
Remember, responsibly! I don't want any of you fiddling with these things in an inebriated state to the point where you're in the ER telling the doc about your "one in a million" Seinfeld nether region accident. [Swarm via Boing Boing]
