"It is illegal to carry any sharp or bladed instrument in a public place (with the exception of a folding pocket knife, which has a blade that is less than 7.62 cm (3 inches)). ... However, possession of a lock knife in a public place without reasonable excuse is an offence."
What is a reasonable excuse? I've carried a 3" lock knife with me every day for the past 10 years. It is an essential tool that gets used every day for anything from opening a letter to cutting baling twine to whittling wood. If mr plod ever questioned my carrying of said knife and wanted to confiscate it, I'd be very upset.
Looking in to knife laws, it seems several of the blades I own are illegal in the UK now. I'd happily hand them in to an amnesty but there's no way I'd want to lose my lock knife. I'm not sure why the fact that a knife locks makes any difference as you can buy a fixed blade of any length. What's this country going to be like in 20 years? :angry:
