Selling Knives & Blades - The Law
The laws about buying and carrying a knife depend on the type of knife, your age and your circumstances.
Basic laws on knives
It is illegal to:
- sell a knife of any kind (including cutlery and kitchen knives) to anyone under 18. To purchase knives from this site you must be over eighteen years of age. It is a criminal offence to sell knives, knife blades or razor blades to anyone under the age of eighteen. When placing an order for knives, knife blades or razor blades, the buyer will be asked to declare that they are of the appropriate legal age. If we discover that the buyer is not permitted to purchase knives, knife blades or razor blades or that a price given was made in error we are entitled to cancel the order immediately, without notice.
- carry a knife in public without good reason - unless it’s a knife with a folding blade 3 inches long (7.62 cm) or less, eg a Swiss Army knife
- carry, buy or sell any type of banned knife (the list of banned knives is below)
- use any knife in a threatening way (even a legal knife, such as a Swiss Army knife)
- Lock knives (knives with blades that can be locked when unfolded) are not folding knives, and are illegal to carry in public without good reason.
The maximum penalty for an adult carrying a knife is 4 years in prison and a fine of £5,000.
Good reasons for carrying a knife
Examples of good reasons to carry a knife in public can include:
- taking knives you use at work to and from work
- you’re taking knives to a gallery or museum to be exhibited
- the knife is going to be used for theatre, film, television, historical reenactment or religious purposes (eg the kirpan some Sikhs carry)
- A court will decide if you’ve got a good reason to carry a knife if you’re charged with carrying it illegally.
