I am traveling light to Greece (carry-on only) and would normally pack a "picnic knife" with a corkscrew/opener in with my checked baggage. Does anyone know of any plastic/ceramic knife/screwdriver/bottle opener object that will go through security? I have couple of "sporks" for eating yogourt etc. but they don't work so great for cheese unless it is really runny, and are obviously useless in opening a bottle of wine. I can always buy one there and give it away, but I'd rather "pack".
