As I mentioned earlier, I carry a portable corkscrew in my carry on bag, the kind where the corkscrew is in a tube and the tube removes and then goes through a hole in the top of the corkscrew to become the handle. The one downside is the occasional hard to remove cork, one of which rests in my hotel room right now. Couldn't get it out last night, no matter how hard I pulled. Tonight I'll take it downstairs to the hotel bar and see if they will open it for me...probably charge me a corkage fee...
