You can bring a safety razor handle through TSA security in your carry-on, but the blades themselves are strictly prohibited. According to 2026 TSA guidelines, if you have a traditional safety razor with a removable blade, you must remove the blade and pack it in your checked luggage or discard it before reaching the checkpoint. The metal handle is perfectly fine to carry on. This is a common point of confusion because disposable razors and cartridge razors (like those from Gillette or Schick) are allowed in carry-on bags because the blades are permanently encased in plastic and cannot be easily removed to be used as a weapon. Electric razors are also fully permitted in both carry-on and checked bags. If you are an avid safety razor user and only traveling with a carry-on, your best strategy is to mail the blades to your destination in advance or purchase a fresh pack of blades at a local pharmacy or specialty shop once you have cleared the airport security area.
