TSA Rules: Bringing Knives in the USA

Because you are planning to travel with a knife, it becomes important for you to check the TSA rules because TSA is a U.S. government agency that is responsible for the safety and security of all passengers at all airports within the United States.

TSA has a few rules, especially for knives, just like it has various rules about bringing nail clippers and scissors on planes in carry-on or checked luggage.

According to TSA, you can’t carry any types of knives in your hand luggage; they are all banned in carry-ons except a few, like plastic knives and round-bladed butter knives. But all types of knives, irrespective of size and quantity, are allowed in checked luggage.

TSA also says that when you pack knives in checked luggage, the most important thing you must keep in mind is that they should be securely wrapped and the edges should not be exposed so that they don’t accidentally cause harm or injury to any of the TSA agents.

Are you allowed to bring a knife in your carry-on?

No, in the USA, you’re not allowed to bring knives in your carry-on luggage. TSA, on their official website, has restrictively prohibited carrying knives in hand or carry-on luggage.

However, in other countries, rules vary because of many factors. Some countries allow bringing knives up to a certain size in a carry-on, while others restrict them and allow them only in checked luggage, like the USA.

We’ll take a closer look at different countries and their rules in a bit, so keep reading or you can directly jump to the section “Rules for Knives in Other Countries.”. We’ve covered different countries; most likely, you’ll get the answer there for your country.

Are you allowed to bring a knife to your checked luggage?

Yes, you’re allowed to bring knives with you in your checked luggage, regardless of size and quantity. But they must be wrapped securely to avoid any harm to TSA officers and agents.

This is because TSA has explicitly mentioned on their official website that if you plan to carry a knife in your checked luggage, make sure that it’s securely wrapped. TSA officers and agents sometimes do additional inspections of any suitcase whenever they need to.

In this case, if you carry a bare knife that is unwrapped, it can potentially harm the security officer. If, unfortunately, it happens, you’ll be in trouble, so always keep in mind to keep your knife secure and wrapped.

TSA hasn’t mentioned any guidelines about the size and quantity of knives, which means you can easily bring normal-sized knives in a reasonable quantity, obviously in your checked luggage.

Rules for Knives in Other Countries

United Kingdom

For hand luggage, the United Kingdom aviation authorities only allow knives to have a length of no more than 6 cm (2.36 inches), and the end of the blade should be blunt.

If you want to have a sharp knife or a knife with a more than 6 cm blade, you’ve got to check it in your checked luggage. But keep in mind that the final decision always rests in the airline officer’s hands, so you might be asked to keep your knife even smaller than the allowed size in your checked luggage.

Therefore, I’d recommend you keep your knife in your checked luggage; regardless of the size or length of your knife, it’s more secure and peaceful.

Canada

The same goes with Canadian Airlines; if the blade size of your knife is under 6 cm or 2.36 inches, you’re allowed to bring it in your carry-on luggage, but if it exceeds the limit of 6 cm, you’ll have to keep it in your checked luggage.

Concealed or disguised knives, like knives hidden in a belt, comb, or any other object, are not allowed, neither in carry-ons nor in checked luggage. If you’re caught with these types of knives, you might be in big trouble as they’re illegal.

And the same thing applies over here as well, as I explained above about the UK airlines.

Europe, China, Australia and India

European countries, India, China, and Australia, follow some similar rules that the USA follows: no knives are allowed in hand luggage, regardless of type or size. Knives are allowed to be carried only in checked luggage.

Tips on how to pack knives securely in your checked luggage?

TSA or any other airport security always advises you to wrap your knives securely so that the inspection officers or baggage handlers don’t get harmed. If, unfortunately, they get harmed because of your mistake, you’ll get into serious trouble.

So it’s highly recommended to safely pack your knife in such a way that the edges of the knife are not exposed. There are many ways in which you can safely pack your knife in your checked luggage so let’s take a look.

By Using Paper and Tape: First of all, take some paper and wrap it around the blade of your knife so that it can act like a layer between the tape and the blade so that there should not be any remaining glue on the blade when you open it.

Once you wrap the paper, wrap the tape around the blade, ensuring that the edges of the blades are totally covered. When the wrapping is complete, inspect the entire blade to make sure that nothing is unsafe or harmful.

Using a hardside box: You can use a solid box to put your knife inside; this is the most secure method you can use. It’ll not only keep your knife secure but also the belongings around the knife; that’s why it’s the most recommended method.

Using a Knife Holster: You can also use a dedicated knife holster to pack your knife inside. You can easily get it from your nearby offline or online store.

What if my knife is confiscated by airport security?

If you’re unfortunate enough that your knife is confiscated, in this case, you’ll have to keep a few things in mind and follow them accordingly.

Stay Calm and Peaceful: The first thing is to be peaceful and calm; don’t lose control over yourself. Don’t argue with the TSA or any other airport security; they’re doing what they’re supposed to do. By being more organized and peaceful, you can do much better and overcome this issue.

Review the entire event: Think for a minute: if the confiscation is valid, if the answer is yes, leave the knife and continue your journey because you don’t have any options left. If you try to argue with them over a banned knife, it might leave you with a serious problem.

Discuss with the supervisor: But if you think your knife follows all the guidelines of the airline you’re flying with and the confiscation is invalid, you can ask a supervisor or a higher authority. Hopefully, they’ll review the entire situation and decide what to do.

Look for the way out: In the case of confiscation, you’ll be left with only three options. One is to surrender the knife and continue your journey. The second is to hand over the knife to any relative who is at the airport and not flying with you. The third option is that you can mail it to your desired location. You can opt for any options that best suit your situation.

Do your own research before you fly. In order to be secure when flying and avoid any confiscation, it’s highly recommended that you do your own research through the official website of the airline so that you don’t have any misconceptions.

Pack Your Knife Securely: If you’re packing your knife in your checked luggage, make sure that any edges of the knife are not exposed because they can cause harm or injury to inspection officers or baggage handlers. If, unfortunately, it happens, you’ll be in big trouble, so make sure to pack it securely.

Final Thoughts: Can you bring a knife on a plane?

So, the answer to the question “Can you bring a knife on a plane?” is yes, but if you want to carry a knife in your carry-on luggage, it’s not allowed in the USA. You can carry your knife in your checked luggage, but with certain conditions, as we explained above.

When you pack your knife in your checked luggage, make sure your knife is securely wrapped and none of the edges are coming out of the wrapping. This is important to keep in mind because TSA has especially mentioned it on its official website.

It’s highly recommended to check out the official website of the airlines you’re planning to fly with because the rules vary for different countries and different airlines.
