What survives airport security

All knives other than round-bladed/blunt butter knives or plastic cutlery are barred from the checkpoint, regardless of blade length, lock or opening type. Pack in checked bag. Final say rests with the screening officer; any item may be refused or surrendered even if listed as allowed.

Allowed in checked bags if sheathed or securely wrapped. Check destination-country weapons laws.

Source

EU-level Attachment 4-C bars knives with blades of more than 6 cm; blades of 6 cm or less are not on the EU list. Member states, airports and airlines may be stricter (Art. 6 of Reg. 300/2008), so check the departure airport. UK is stricter. I did not verify any EU state stricter than 6 cm. Final say rests with the screening officer; any item may be refused or surrendered even if listed as allowed.

Source

EU Attachment 5-B bans only explosives/incendiaries in hold, so knives are not barred by EU rules; airline permission, wrapping and destination laws apply.

Source

UK is STRICTER than the EU 6 cm rule: gov.uk bars any knife with a sharp or pointed blade, OR a blade longer than 6 cm. So a short pocket-knife with a sharp/pointed blade is still barred. Final say rests with the screening officer; any item may be refused or surrendered even if listed as allowed.

Source

Allowed in hold with airline check. England & Wales public-place knife law applies on the way to the airport: pack it in the checked bag before leaving home (not verified in this research).

Source

Blade 6 cm or less: allowed in carry-on within Canada and to non-U.S. international destinations ONLY. No knives of any type or length in carry-on on flights to the U.S. Automatic/gravity/centrifugal or button/spring-opening knives and concealed knives are prohibited items (illegal under the Criminal Code; police may be notified). Final say rests with the screening officer; any item may be refused or surrendered even if listed as allowed.
