Yes, bottles open with anything to pry with. For me that usually ends up being the swiss army knife I try to carry whereever I go (never know when I'll need a bottle opened) lol...
Haven't tried the wine cork thing. Needed it one day when I decided to have some wine with friends and they didn't have a corkscrew, neither did I. That turned into quite an ordeal. Imagine 3 people passing a bottle around trying to remove cork with anything that can be found that isn't a cork screw, including some screws, and similar stuff... I would've just had something else to drink instead but by the point I was ready to give up there was a part of me telling myself that bottle will not defeat me... Ultimately it did not... Funniest part of that story is the fact that in the store I figured we had a cork screw because I specifically thought my swiss army knife mentioned earlier had a cork screw. I mean who ever saw a swiss army knife without a corkscrew right? I didn't check it when I could've gotten one. Got home, realize they put a philips screwdriver in there where the corkscrew usually is. I never noticed before that...
