Razors on a Plane: TSA Carry-On and Checked Bag Rules

Where these numbers come from

Razors are allowed in carry-on bags when the blade is fixed in the handle. Disposable razors and modern cartridge razors pass through checkpoints every day. There is no limit on how many you bring, and they can stay in a toiletry pouch on the belt.

Safety razors and straight razors are where travelers get stopped. The handle of a double-edge safety razor is allowed in a carry-on, but the blade must be removed before you reach the checkpoint. Officers will not take the blade out for you. Loose blades, whether for a safety razor or a straight razor, belong in checked baggage.

In checked bags everything is allowed, but sharp items should be sheathed or wrapped. Slide loose blades into the original dispenser or a blade bank, or tape them into a folded piece of card. That protects baggage handlers who open bags for inspection.

Electric shavers sit in a third category. They are permitted in both bags. A shaver with a built-in lithium battery is safest in the cabin, where any battery problem can be handled quickly. Spare lithium batteries are carry-on only, which is covered on the portable chargers page.

Shaving cream is the usual surprise. A 6-ounce can exceeds the 3.4-ounce carry-on limit and is best checked, with its cap on and within the 18-ounce, 70-ounce toiletry limits. A worked example: a razor, a 3-ounce gel and a travel aftershave balm all fit in one quart bag, while a full-size can moves to the hold. More on the math is on the liquids rule page.

Some airlines and airports abroad add their own limits on straight razors, so check your route. If you use a straight razor daily, plan to check a bag or carry a cartridge razor as a backup. Use the can I bring it finder for other grooming gear. Travelers often ask about travel kits sold as sets. A boxed set with a safety razor, brush and a sealed pack of blades splits cleanly: the razor handle goes in the carry-on without a blade, and the blade pack goes in the checked bag. If you fly carry-on only, choose a cartridge or disposable model and treat the safety razor as a home-shaving tool.
