I don't prefer the Victorinox corkscrews. Just not a good idea, IMO, to be pulling with 100lbs of force on that little hinge.

Just pack a small corkscrew. They're not too big. Unless you're talking about literally EDC, and not "at the hotel after work." then I guess you're stuck with a SAK. I like my camper, never felt the need for a lock on them.
