Common questions
Any knife found in carry-on baggage will be confiscated at the checkpoint with no exceptions — this includes pocket knives, Swiss Army knives, penknives, and multi-tools with blades. You will be given the option to return to check-in and put the item in a checked bag if time allows, but if you are past the point of no return the knife will be taken permanently. There is no discretion on this rule.
Knives are banned from carry-on baggage in all 14 regions we cover — there are no regional exceptions that permit any blade, no matter how small or how it is designed. This consistency makes knives unusual among restricted items. Every type of knife, including decorative, ceremonial, or utility versions, must travel in checked baggage.
Yes. Any multi-tool that contains a blade is treated as a knife regardless of whether the blade is folded, locked, or small. Screeners will see the blade in the X-ray and will remove the item from your bag. If your multi-tool has no blade — just tools like a screwdriver, file, or pliers — it may be permitted, but check the specific tool's configuration before traveling.
Wrap knives securely so the blade cannot shift during transit and cannot cut through the bag or injure baggage handlers. A hard-sided case or a blade guard is the best option. There are no specific TSA rules on how to wrap a knife in checked baggage, but airlines can refuse bags that pose a handling risk, so secure packaging is strongly recommended.
