Sharp Objects: Carry-On vs. Checked

Disposable and cartridge (safety) razors are allowed in carry-on bags. Straight razors and loose razor blades (not in a cartridge) are not allowed in carry-on and must be packed in checked baggage.

Scissors with blades shorter than 4 inches (measured from the pivot point) are generally allowed in carry-on. Longer scissors must go in checked bags.

Knives of any kind are generally not allowed in carry-on — including pocket knives, box cutters, and kitchen knives — and must be packed in checked baggage. A narrow exception exists for plastic or round-bladed butter knives.

When in doubt about a specific blade, checked baggage is always the safer choice.
