Can You Bring Knives On Planes?
Yes, you can bring knives on planes, but with a few restrictions on types and packing. In the United States and European nations, TSA prohibits knives in carry-on luggage, except for plastic or round-bladed butter knives. However, blades can be packed in checked baggage if they are sheathed or securely wrapped to deter injury during air travel.
Current UK law states: “carrying knives or any weapons in public without a ‘good reason’ is illegal”. So it’s understandable that airlines enforce strict rules on bringing such items on flights.
Sharp or pointed blades over 6 cm are not allowed in hand luggage in the UK. But you can pack them in hold luggage after consulting with the airline.
Additionally, bladed tools such as box cutters in carry-on luggage are banned. However, certain items like straight razors are still allowed if packed in a specific way.
TSA Guidelines for Packing Sharp Objects in Checked Luggage
The TSA (Transportation Security Administration in the USA) has the following regulations on its website with regard to the limitations on sharp objects in carry-on luggage:
“TSA officers have the discretion to prohibit any item through the screening checkpoint if they believe it poses a security threat. Any sharp objects in checked bags should be sheathed or securely wrapped to prevent injury to baggage handlers and inspectors.”
TSA guidelines for packing sharp items in checked luggage include:
- Use a sturdy container or protective sheath to prevent the sharp object from damaging other items in your luggage or injuring baggage handlers.
- Wrap the sharp item in a soft material, such as clothing or bubble wrap, to prevent it from shifting or jostling during transport.
- Declare any sharp items or potential weapons, including tools or sporting equipment, to the airline and TSA agent at the security checkpoint.
- Failure to declare sharp items or other prohibited items could result in fines, delays, or even criminal charges.

TSA also imposes civil penalties on individuals who bring sharp items, including knives, through airport security checkpoints, sterile areas or onboard aircraft. The amount of the fine can vary from $390 to $2,250. In addition to the civil penalty, the TSA may refer the matter to law enforcement for possible criminal prosecution.
Note: Always check the TSA website or mobile app for the most up-to-date information on prohibited items and restrictions on sharp objects. Regulations may vary based on airline, destination, or other factors.
Types of Knives Allowed in Checked Luggage
You're a traveller who enjoys outdoor activities such as camping or hunting. You may want to bring along a knife for such purposes. While knives are generally illegal to bring in carry-on luggage, certain types are permitted in checked baggage.
- Fixed Blade Knives: These knives have a blade permanently attached to the handle. They are allowed as long as the blade is within 7 inches. They are allowed because they are considered tools and used for various purposes, such as camping, hunting, and fishing.
- Folding Knives: These knives have a blade that folds into the handle. Folding knives are allowed, providing the blade is no longer than 4 inches.
- Pocket Knives: These knives are commonly utilised as tools for outdoor activities like camping, fishing, and hunting, as well as for day-to-day tasks such as opening boxes or cutting loose threads. For this reason, they are not inherently hazardous and are not perceived as a risk to airline security.
- Kitchen Knives: These knives are essential tools for cooking and are commonly used in households and professional kitchens. While they can be dangerous if not used properly, they are not inherently a security threat and are unlikely to be used as weapons on board an aeroplane. However, certain kitchen knives, such as those with serrated or curved blades, may be subject to additional scrutiny by some airlines or destinations.
- Multi-tools: These tools have numerous functions, including knives, and are permitted provided that the blade’s length does not exceed 2.36 inches.
- Note: Remember that any knife with a blade longer than the specified lengths above is strictly banned in checked luggage. Additionally, any knife that is deemed to be a weapon, such as switchblades or daggers, is prohibited in both carry-on and checked luggage.
Types Of Knives Prohibited On Planes
Certain knives can be deemed unfit depending on their blade size, structure, and other factors. If you were to carry one of these knives in your checked luggage during air travel, the airport security officer would probably contact the relevant authorities. You could face legal consequences.
The regulations can be intricate and vary from country to country. We have gathered a list of knives that are generally considered outlawed by most governing bodies.

- Switchblades: These knives have a blade that can be quickly released with the push of a button. They are banned on planes because they are considered to be weapons and can be used to harm others.
- Balisongs or butterfly knives: The blade of these knives can swing out from the handle. You must not bring these on planes because sometimes they are believed to pose a security threat.
- Disguised knives: These knives are designed to look like other objects, such as a pen or a belt buckle. They are not permitted on planes because they can be easily concealed and used to injure others.
- Throwing stars or ninja stars: These throwing weapons are prohibited from being carried on planes due to their potential to harm others.
- Straight razors: Their non-retractable long sharp blades can be used as weapons.
- Swords or sabres: Most countries prohibit sharp weapons such as swords, sabres, and even spears.
Tips for Safely Packing Knives in Checked Luggage
According to airline security regulations, all travellers must securely pack knives in their checked baggage. You must shield the blade to prevent unintended harm when people handle or inspect the luggage.
If you fail to safely pack a knife and a security officer sustains injuries as a result, you may potentially encounter legal action.

Therefore, we have recommended various tips for safely packing knives in checked luggage, which are:
Choose The Right Luggage
When packing knives, choose sturdy and durable luggage with a hard shell. This will help protect your knives from damage during transit and will also help prevent them from being lost or stolen.
Pack The Knives Separately
When packing multiple knives, pack them separately in their own protective covers or sheaths. This will help reduce the possibility of scratching or damaging them during transit. To take it further, you may want to put it in a separate bag for additional safety measures.
Use Tape To Secure The Sharp Edge
Tightly encircle the blade with paper or napkins to create a barrier between the knife and the adhesive portion of the tape. This will ensure that the blade remains free of any sticky residue. The next step is to cover the knife with duct or masking tape to secure everything in position.
Pack The Knife In The Middle Of Your Luggage
Place the knife in the centre of your baggage, enveloped by gentle objects like clothes or towels. This will offer additional padding and also prevent the knife from moving around while being transported.
Keep Your Luggage Locked
Use a TSA-approved lock to secure your luggage, especially if it contains knives or other sharp objects. This will help hinder theft and will also allow TSA agents to inspect your luggage without damaging it.
Place The Knife In A Hard-Sided Container
This will offer supplementary protection for the knife and will also ensure the safety of your baggage in case the knife accidentally pierces through something.
