knives are generally not allowed to be carried onboard cruise ships, including those operated by Cunard Line, as part of their security and safety measures. Cruise lines typically have strict policies on items that passengers are allowed to bring on board, and sharp objects like knives are usually prohibited in the public areas of the ship.
However, there might be exceptions for specific types of knives, such as small pocket knives with non-locking blades or culinary tools used by professional chefs. These exceptions are subject to the cruise line's discretion and regulations. If you have a specific reason for needing a knife on your cruise, such as professional culinary work, you should contact Cunard Line or the cruise line you plan to travel with in advance to inquire about their specific policies and any necessary approvals.
Keep in mind that cruise line policies may change over time, so it's essential to verify the most current rules and regulations regarding items allowed onboard before your scheduled travel date. You can find this information on the official website of Cunard Line or by contacting their customer service directly.
