In 2026, most major cruise lines like Royal Caribbean, Carnival, and Disney generally permit passengers to bring a wine corkscrew in their luggage, provided it does not have a large, exposed blade. Standard "waiter-style" corkscrews with a small foil-cutting blade (usually under 4 inches) are typically allowed. However, rules can be stricter for carry-on bags versus checked luggage; security may occasionally confiscate them at the terminal if the blade is deemed a safety risk. Interestingly, many travelers find they don't actually need to bring one. If you take advantage of the standard allowance (usually two 750ml bottles of wine per stateroom upon embarkation), your room steward can provide a corkscrew upon request, or you can have the bottle opened at a shipboard restaurant for a "corkage fee" (typically $20–$30). If you are particularly attached to a high-end corkscrew, it is safest to pack it in your checked bag to avoid any scrutiny during the initial security screening at the cruise terminal.
