Whether you can fly with a Leaf razor in 2026 depends entirely on your luggage choice. A Leaf razor is a "safety razor" that uses double-edge blades snapped in half. According to TSA and international aviation standards, you cannot have the blades in your carry-on luggage because they are "loose" and easily removable. You can bring the metal razor handle (without blades) in your carry-on, but any blades must be securely packed in your checked baggage. If you are a "carry-on only" traveler, you must purchase blades at your destination. This rule is a high-value safety protocol to prevent sharp, unshielded objects from entering the cabin. For a 2026 "pro-move," many travelers use a dedicated blade tin to store their Leaf blades in their checked bag, ensuring the sharp edges don't cut through their vanity kit or pose a risk to baggage handlers during a potential manual search.
