Can I take a Swiss Army Knife on a Carnival cruise?

Carnival allows its passengers to carry swiss army knives but the blade has to be less than 4 inches. Royal Caribbean completely prohibits its passengers to carry any form of knives or blades in their luggage aboard the ship.



In 2026, you generally cannot take a standard Swiss Army Knife on a Carnival cruise if the blade exceeds the strict length limit. Carnival’s prohibited items policy allows for small, non-locking pocket knives only if the blade length is less than 4 inches (approx. 10 cm). However, many Swiss Army models feature locking blades or additional tools that might be scrutinized by security. Furthermore, international ports and "Zero-Tolerance" security strategies in 2026 have become increasingly aggressive; carrying even a small blade can lead to additional screening or confiscation during embarkation. It is professionally recommended to leave multi-tools and pocket knives at home to avoid delays. If you must have a tool, ensure it is a "TSA-compliant" version with no blade, or be prepared to have it held by ship security until the end of the voyage.

Contrary to people who want to believe that the ships are armed but the cruise lines don't want to tip their hand to the terrorists, there is in fact no hidden cache of weapons ready to be deployed by the cruise ship's security forces. Cruise ships are flagged in foreign countries like the Bahamas or Panama.
