Can I Put A Knife In My Checked Bag?

You’re wondering as you pack for your forthcoming flight. Can I put a knife in my checked bag?

Flammables and explosives are two examples of objects that are forbidden on planes. What about knives, though? Can you put knives in checked luggage and transport them on planes? 

Here is the applicable TSA knife regulation for all other knives:

All knives must be stowed in checked luggage, according to TSA! Knives are prohibited in carry-on luggage. To protect baggage handlers and examiners from harm, all sharp objects inside checked bags must be coated or securely wrapped. The TSA officer has the final say about whether or not an item can pass through the checkpoint.

To be completely honest, even if the TSA says you can, I don’t recommend traveling with a flat, rounded metal butter knife.

All of these inquiries will be addressed in this article, along with others that are connected, including international knife legislation, how to store knives in bags, how to prevent knife theft, and more.

Let’s get into it!

Can I Put a Knife in My Checked Bag?

When flying, it’s necessary to think about which items can be checked into luggage and which ones need to be brought on board. This often involves putting a knife inside the checked luggage of the person. There are several considerations to make while putting a knife inside checked baggage, though.

It’s critical to confirm with the airline any limitations on knives inside checked baggage. Blades are not permitted on some airlines, and others may have limitations on the kind or size of knives that can be brought.

If the airline company does permit weapons in checked bags, they almost certainly will have requirements for how the blades must be stowed. For instance, the knife might have to be kept in its sheathed case or may need to be stored in a hard-sided box.

It’s crucial to keep in mind that the TSA’s 3-1-1 rule still applies even if a knife is permitted in checked luggage. 3.4 ounces (100 milliliters) or fewer containers must be used for all liquids, gels, and aerosols, and each of these containers must be put inside a single, clear, quart-sized bag.

Finally, it’s important to understand that even though a knife is put in checked luggage, the TSA may still find it while conducting a security check. The knife would be taken away and you could have to go through more screening if this happens.

Therefore, if you intend to bring a knife in any checked luggage, ensure that you check with the airline company first and pack it by TSA regulations.

Legal Problems With Flying With Knives

Verify that the knife you intend to carry is permitted in the area where you’re traveling.

The knife may be lawful to pack inside your checked luggage and to carry in your native state, but the moment you pick up your luggage at your destination, you could have a prohibited concealed knife.

Check to see if it’s permitted where you’re heading!

Do you know? What is this knife’s function? Is it one of these weapons:

  • Automatic knives
  • Knives That Slash Balisongs
  • Pocket knives
  • Knives that shoot

Confirm the knife laws of the nation you intend to visit if your knife is a lethal or dangerous weapon. This extremely helpful tutorial was created by Knife Up.

Additionally, if you are traveling abroad, confirm the country’s knife legislation. Not all nations are as permissive about carrying guns as the US is.

You might be questioning whether you have to disclose the knife when checking your luggage nowadays that you know you must carry any knives in checked baggage.

Should Knives Be Declared in Checked Baggage?

In the US, a securely wrapped knife that is in checked luggage does not need to be declared. Guns are subject to various regulations and must always be declared. Just make sure to pack Secure your knife securely and safely to prevent injury to anyone who opens your bag during a search.

What! A Pocket Knife Must Be Allowed on Airplanes, Right?

Swiss army knives, Exacto knives, pocket knives, small pocket knives, and pen knives are currently prohibited in the cabin on US flights. It’s easy. A butter knife is the only option.

The TSA intended to permit carry-on luggage for pocket knives with blade lengths below 2.36 inches in 2013. 

In 2013, the Union of Flight Attendants launched a campaign to halt this plan, and in 2017, a law was passed to prevent the TSA from ever again permitting knives in the cabin of airplanes.

The Varieties of Knives Which Are Prohibited on Airline Flights:

Most nations and U.S. states prohibit the use of certain types of knives. Most frequently, they are prohibited due to a concealed blade, an excessively long blade, or serious injuries that are more severe than those caused by a standard knife. These knives shouldn’t be packed; instead, look into alternate shipping options like USPS or FedEx.

Throw Knives (Illegal):

Flick knives often called switchblades or automated knives, contain a hidden blade that emerges upon pressing a button. We do not advise traveling with these knives because they are outlawed in many states and nations.

Bumblebee Knives (Illegal):

Butterfly knives are awesome and would make fantastic gifts or souvenirs, but most states and nations have laws against them.

False knives that look like other objects, such as pens or lighters (Illegal):

Fantastic gifts would be lighter knives or spy-style knives that resemble pens, but sadly, they are prohibited practically everywhere. Therefore, avoid putting them in your luggage to avoid getting into difficulty.

Death Stars, throwing knives, and throwing stars (Illegal):

Knife throwing is now essentially a sport, and those who participate in it have a tough time getting to competitions because death stars and throwing knives are outlawed in most states. Knives and rubber-throwing stars, both of which are acceptable methods, have been mentioned.

Push Knives (Illegal):

Instead of a typical, parallel handle, push daggers to have one that is perpendicular. They were widely used as a personal defense tool by civilians a few decades ago. But they are against the law in many places, so don’t try to bring them with you in your luggage. However, they are prohibited in many nations and jurisdictions, so avoid attempting to pack them in your luggage.

Long-bladed fixed-blade bowie/hunting knives (Illegal):

Whereas most single-blade knives remain generally lawful, others with longer blades or tougher edges are prohibited in many states and nations. Never pack one without first consulting the authorities.

Swords and machetes (Illegal):

In the past, machetes and swords were often kept in homes for self-defense. Today, however, they are illegal in many countries and areas. For instance, most machetes are illegal in the UK since they are longer than 50 cm. 

They are legal in many states in the U.S. and in other countries where they are used to cut carry-on bags. If somehow the cutlery set is valuable, you should probably go with option 2, as things occasionally tend to “disappear” in checked baggage.

What Requirements Apply to Knives on International Flights?

Check the guidelines for The airline regulator while going internationally.

There are endless nations and states that you will cross in flight. For instance, you must research the knife regulations of the UK, Georgia, and Texas. 

If you are traveling by plane from London, United Kingdom, to Dallas, United States of America, with a stopover in Atlanta, United States of America.

TSA Knife Rules (Transport Security Administration/USA):

Round-bladed plastic butter knives are permitted in hand luggage, according to TSA, which oversees airlines flying within the United States. No special type of knife is prohibited, but all other knives must be securely stowed within checked baggage.

IATA Knife Rules (International Air Transport Association/Worldwide):

All blades cannot be brought on board in hand luggage, according to the IATA, an organization that oversees 82% of air traffic. Any type of knife is permitted in checked baggage.

Knife Rules of the CAA (Civil Aviation Authority/UK):

Penknives (pocket knives) with blades smaller than 6 cm (2.4 inches), which are permitted in hand luggage by CAA, which oversees airlines operating in the UK, are prohibited. Multitools are also prohibited, even if their blade length is less than 6 cm. Any other style of the knife may be brought without restriction in checked baggage.

Knife Rules of the TCCA (Transport Canada Civil Aviation):

knives with blades below 6 cm (2.4 inches), which are allowed in hand luggage by the TCCA, which oversees airlines operating in Canada. All other kinds of knives must be placed in checked baggage.

How to Prevent Having Your Knife Stolen from Checked Luggage?

It is common knowledge that many airport staff is searching for expensive, simple-to-steal things like knives and perfume. I’ve never had anything taken from my bag, but the majority of people who travel a lot have. You essentially have no recourse because airlines frequently refuse to accept responsibility. 

So how can you stop people from stealing your expensive knives? 

To begin with, never bring knives that you are worried about losing or that are priceless. I would advise getting additional insurance for the contents of your suitcase or using FedEx if your knife is worth more than $100.


I hope you found the solution to your question, “Can I Put a Knife In My Checked Bag?” 

I normally try to avoid carrying blades through airport security!

However, you must ensure that your blades are not included in your carry-on when interacting with TSA to avoid paying a hefty charge. Additionally, keep in mind that the other cutting tools might not be permitted in your carry-on, so always be alert for limitations.
