Small knives permitted in carry-on luggage must meet all of the following requirements:

- The blade must be no more than ½ inch in width
- Knives with locking or fixed blades

If a passenger is unsure if an item meets the above requirements, TSA recommends that the item be placed in checked luggage.
The final decision rests with TSA on whether to allow any items through security checkpoints.
