Can I bring a multitool on a plane?

No, you generally cannot bring a multitool in your carry-on if it has a blade. In the US, security rules explicitly prohibit multitools with knives of any length in carry-on bags. You must pack them in checked luggage. The rules vary internationally, with some countries allowing small blades under 6 cm, but the safest approach is always to put your multitool in checked baggage.

US: Multitools with blades of any length are prohibited in carry-on. Multitools without blades are allowed. Scissors on the tool must be under 4 inches.
Canada: Multitools with blades under 6 cm (2.4 inches) are permitted on domestic and international flights, but are banned on US-bound flights.
Europe: Folding blade knives under 6 cm are generally allowed, but multitools are often treated as tools and may be confiscated. Airport security has final discretion.
UK: Small scissors under 6 cm are allowed, but multitools with pliers or screwdrivers are often prohibited due to the tool function.
Gulf, Turkey & Asia-Pacific: Major carriers prohibit bladed multitools in the cabin. Always check with your specific airline before traveling.

Detailed Answer

US Rules

In the United States, security rules are strict and clear regarding multitools. Multitools with knives of any length are prohibited in carry-on bags. This applies to all blades, regardless of how small they are. The presence of any blade makes the entire tool prohibited. You must pack these items in your checked luggage.

However, there is an exception. Multitools without blades are permitted in carry-on bags. This includes tools that only have pliers, screwdrivers, files, and other non-bladed implements. Similarly, multitools with scissors that have blades under 4 inches are allowed.

Some multitool brands have identified certain models as complying with carry-on requirements. These include bladeless models that only have pliers and other non-cutting tools. However, the final decision always rests with the security officer on duty, and even compliant tools may be subject to additional inspection or confiscation.

Canada

Canadian rules are more lenient than those in the US. Small folding knives with blades of 6 cm (2.4 inches) or less are permitted in carry-on bags on domestic and international flights. This includes multitools with blades that meet this length requirement.

However, the rules change for flights to the United States. For US-bound flights, knives of any type or length are not permitted. For these flights, you must pack your multitool in checked luggage.

Europe and the UK

European rules are more ambiguous than those in North America. General security regulations prohibit knives and other sharp objects in hand luggage. Tools that could cause serious injuries are explicitly listed as banned at some airports.

However, there is an exception for small folding blade knives under 6 cm. These are generally allowed in the cabin on flights within Europe. The rule is different for the UK. While the UK technically allows knives under 6 cm, multitools with pliers, screwdrivers, and other implements may be banned because they contain other implements with a sharp point.

In all European countries, the final decision rests with the local security team at the airport, and they have broad discretion to determine what is allowed onboard.

Gulf, Turkish, and Asia-Pacific Carriers

For Gulf carriers like Emirates, Qatar Airways, and Etihad, the general policy is that sharp objects and knives of any kind are prohibited in the cabin. Passengers traveling through major hubs such as Dubai, Abu Dhabi, or Doha should expect to place multitools with blades in checked baggage. Turkish Airlines follows similar strict rules for cabin baggage.

In Asia-Pacific, airlines like Singapore Airlines, Cathay Pacific, Japan Airlines, and Korean Air generally prohibit knives and bladed tools in carry-on luggage. Passengers should always check with the specific airline, as rules may vary depending on the destination and local regulations at transit points like Singapore Changi, Hong Kong, Tokyo Narita, and Seoul Incheon airports.

Checked Baggage and Packing Advice

The safest and most reliable way to travel with a multitool that contains a blade is to pack it in your checked luggage. You should always put the multitool in its sheath before packing it in your bag. If you don't have a sheath, you can wrap it in a handkerchief or soft cloth to prevent it from causing injury to baggage handlers.

If you arrive at security with a prohibited multitool, you have a few options: take it back to your car, check your bag at the airline desk, or surrender it.
