Taking pocket knife out of United Kingdom

Details

A personal pocket knife faces no export formality from United Kingdom when packed in checked baggage — blades of any size are prohibited from cabin baggage under aviation security rules worldwide. The practical constraints are destination-side: public-carry laws vary sharply (blade-length limits, locking-blade bans, and "good reason" requirements in countries such as the UK), and some jurisdictions treat certain knife types (automatic, gravity, butterfly) as prohibited weapons at import.
