Buying Knives or Bladed Items from Open Air

Under UK law it is illegal for us to sell any knife or bladed object to anyone under the age of 18.

When you buy a knife, or any item that contains a blade (including axes), through this website, you are making a legal declaration that you are 18 years of age or more. Checks will be made, where possible, to determine the age of the recipient of any delivery containing a knife. If we cannot determine the age of the recipient before we despatch the order we will ask for verification such as a picture of a driving license or passport.

Please understand that, in order to comply with the law, if we cannot obtain satisfactory evidence that the purchaser and recipient of an order is not 18 or over we will make a refund for any items that we will not deliver.

Basic laws on knives

It’s illegal to:
sell a knife to anyone under 18, unless it has a folding blade 3 inches long (7.62 cm) or less
carry a knife in public without good reason, unless it has a folding blade with a cutting edge 3 inches long or less
carry, buy or sell any type of banned knife
use any knife in a threatening way (even a legal knife)
In Scotland, 16 to 18 year olds are allowed to buy cutlery and kitchen knives.

Lock knives are not classed as folding knives and are illegal to carry in public without good reason.
Lock knives:

  • have blades that can be locked open and refolded only by pressing a button
  • can include multi-tool knives - tools that also contain other devices such as a screwdriver or can opener
