Do you Have to Declare Knives in Checked Luggage UK?

The question of whether you can take a knife on a plane in the UK depends on  multiple factors. TSA regulations recommend keeping all sharp items, including knives, that could be perceived as a weapon, in checked luggage to comply with any airline security regulations. However, in the UK there are more specific parameters around the size of the knife. Carrying knives with blades longer than 6 centimetres in your carry-on luggage is generally prohibited. This is because knives are considered potentially dangerous and are seen as weapons in-flight. Exceptions may exist for small pocket knives or folding knives with blades under the specified length of 6 centimetres. It is always important to consult and comply with official guidelines provided by the UK authorities and the specific rules of the airline you are travelling with.

The UK government's announcement informs travelers that carrying sharp items without a valid reason is illegal and prohibited during the security checkpoint. Not following these regulations can result in a fine or imprisonment. However valid reasons for carrying knives may be connected to work requirements or national customs that are acceptable to the individual airline. Because there is variance in airline and general policy,  it is essential to familiarise yourself with the specific guidelines provided by the airline you are travelling with and ensure that you have a legitimate reason for carrying a knife. Additionally be mindful of the regulations surrounding knives or sharp items smaller than 6 centimetres. Whilst it is permissible to take some smaller knives on the plane in the UK, regulations may be different between airlines depending on various factors.

• Multi-tools or swiss army knives without knife blades: These products may often come without a knife blade and instead include various functions like screwdrivers, scissors, and pliers. Due to the size and lack of blade these multitools or swiss army knives may be permitted, but it is important to note that if the multi tool or swiss army knife comes with a blade it will be confiscated. 
• Custom or ceremonial knives: In some cases, passengers may be allowed to carry custom or ceremonial knives that are stored in a particular way as determined by the respective airline. These require special authorization and approval of the airline.

• Throwing knives and martial arts weapons: These knives are considered dangerous weapons and are prohibited to ensure passenger safety.
• Disguised or concealed knives: Knives that are designed to be disguised or concealed within belt buckles, pens, shirts or combs, are strictly prohibited on planes. These items are considered concealed weapons and are not permitted for air travel.

Even if you are aware that you can have compliant knives in checked luggage in the UK, when carrying knives on a plane, it is important to follow proper procedures to ensure compliance with security guidelines. Here are five steps to consider:

1. Keep the knives separate: Keeping knives separate or individually stored makes them more accessible and meticulously stored and altogether safer in your carry on bag.
2. Wrap sharp items during travel: To maintain safe hand luggage, carefully wrap sharp items, including knives. This prevents any potential harm from a sharp item piercing a storage container or your luggage, allowing them to be contained-well within the bag. 
3. Use containers: Having a designated container for sharp items is essential. This container provides an additional layer of security and organisation, making it easier to identify and handle the knives during security checks.
4. Declare the knives: Make sure to declare knives or sharp items during security checks or at the check-in counter. Creating transparency helps the authorities understand the nature of the items being carried.
5. Consider alternative luggage options: If possible, it may be more convenient to pack knives in checked luggage instead of carry-on baggage. This helps to minimise any potential issues during security screenings and ensures compliance with airline regulations.
