Packing self-defense tools for a trip requires understanding TSA rules and airline restrictions. This guide explains what you can bring in carry-on or checked bags in 2025 so you can stay safe and travel with confidence.
1. Pepper Spray
Carry-on baggage does not allow pepper spray. Checked baggage may include one canister if it is no larger than four fluid ounces, has a safety mechanism, and is clearly labeled. Self-defense chemicals or tear gas are forbidden. Many airlines still prohibit it entirely.
2. Stun Guns and Tasers
These are not allowed in carry-on bags. You may include them in checked baggage if the battery is removed or secured and the destination permits them. Battery removal is recommended and compliance with airline rules is required.
3. Personal Safety Alarms
TSA permits safety alarms in both carry-on and checked baggage. These devices produce a loud sound when activated and are a legal non-lethal option for travelers.
4. Key Knife
Carry-on bags do not allow concealed blades or key knives. You may pack a key knife in checked luggage. It must be securely wrapped or sheathed to prevent accidental injury.
5. Kubaton
Kubaton devices may be allowed in checked baggage but could be confiscated in carry-on bags. They are hard, tactical tools and pose a risk if inspected by TSA staff.
6. Comb Knife
Comb knives count as concealed blades and are not allowed in carry-ons. They can be carried in checked luggage if securely sheathed.
7. Multi-Tool Card
If your card does not include a blade it may be allowed in carry-on. If it does have a blade, it must be packed in checked luggage. Check TSA lists and your airline rules to be sure.
8. Door Stop Alarm
Door stop alarms are allowed in both carry-on and checked bags. They are useful for hotel safety and trigger a loud sound if someone tries to enter your room.
9. Portable Door Lock
Portable locks that attach to hotel or dorm room doors are TSA-safe and may be packed in either bag. These non-electronic tools pose no risk to airport screening.
10. Car Escape Tool
Car escape tools without exposed blades are typically allowed in carry-on bags. If the tool includes a blade, it must go in checked luggage.
