Just got mine, and the bottle opener works great on it. The thing is beefy too, more than i would have thought, don't have calipers handy to take a measurement but it's pretty much exactly as thick as this quarter I just picked up. I'm really happy with it. Am I going to use it for even half of what it says it can be used for, no way, but I'm stoked on it as a dangler and bottle opener!
