You can take certain types of razors in your carry-on luggage, but the rules depend on the razor type:
- Disposable razors and cartridge razors with the blade enclosed in plastic are allowed in carry-on bags.
- Safety razor handles are allowed, but the sharp blades must be removed and packed in checked baggage.
- Electric razors are permitted in both carry-on and checked luggage.
- Straight razors and loose razor blades are prohibited in carry-on luggage and must be checked.
So, if you want to take a razor in your carry-on, it's safest to bring disposable or cartridge razors or electric razors. Safety razor blades should be packed in checked luggage to comply with security rules.
