Prohibited Items on a Plane: Can You Bring Scissors in Your Carry-on? Are scissors allowed on a plane? It depends. And there's one specific measurement that determines whether you can take them. ✂️✈️ If you don't know the rule, they could be confiscated at airport security. ───────────────────────────── 📏 THE 6 CM RULE The important measurement is the blade length, not the overall size of the scissors. It’s measured from the pivot (the screw that joins the two blades) to the tip of the blade. ✅ 6 cm or less → allowed in your carry-on luggage ❌ More than 6 cm → not allowed in carry-on luggage; pack them in your checked baggage instead. - @lostontheway
