Planes and multitools collide in airport security: you can’t take most Leatherman-style tools through a checkpoint, but there are clear paths to bringing useful gear with you if you plan ahead. This piece explains what typically gets stopped at the TSA line, what can ride in checked baggage, how non-blade tools are treated, and practical ways to avoid losing gear at security. Read on for no-nonsense guidance so your next trip doesn’t cost you a tool or a headache.
First, let’s be blunt: anything with a cutting edge is a red flag for carry-on screening. Transportation security focuses on objects that can be used as weapons, and blades are an obvious example, so most multitools that fold out a knife or have exposed sharp edges are not permitted past the checkpoint. That doesn’t mean every Leatherman is banned — but if it has a blade that locks open, expect it to be taken at the gate.
Not all parts of a multitool trigger the same response. Pliers, screwdrivers, and bottle openers without a blade usually slide through in carry-on, since they aren’t designed to slice. Security officers make judgment calls based on how something appears on the X-ray, so a compact tool that looks like a benign gadget stands a better chance than a bulky instrument with obvious cutting components.
Checked baggage is the safer place for full-featured tools, including those with blades. Most airlines and security agencies allow knives and larger tools in checked luggage because they are inaccessible during flight, which dramatically reduces the risk. Still, packing smart matters: sheathe blades or lock folding tools closed, and stow them where they won’t damage other items or injure baggage handlers.
Rules vary by country and carrier, so planning a trip across borders calls for a quick check of local regulations before you pack. An item allowed in domestic checked baggage might be restricted on some international flights or at certain destinations, and airlines have their own lists of prohibited items too. When in doubt, contact the airline or look up the destination’s transport authority — it beats losing a tool or getting delayed at the gate.
If you prefer to carry something useful in your pockets, choose a blade-free option built for travel. Keychain multitools that trade knives for small screwdrivers, pry bars, and mini-pliers meet most carry-on standards and still cover everyday needs. Another option is to leave the cutting components at home and travel with a pared-down kit that does what you need without tempting security personnel.
At the checkpoint, how you present your gear matters. Place any tool or suspicious item in the bin for screening and answer questions calmly if an officer asks about its function. Confiscations do happen; polite cooperation usually makes the process quicker, and some airports provide receipts for surrendered items so you can appeal or retrieve them later if policy allows.
Finally, consider alternatives to carrying a full tool through airports. Ship a multitool to your destination ahead of time, stash it in checked baggage, or buy a local replacement if it’s more convenient. Those choices avoid the awkward moment at security and keep your travel timeline intact while still giving you the functionality you need on arrival.
