For parents

'007 knife' is street slang for a small, cheap folding lock-knife of a style popular in some UK gangs and prison subcultures. The name comes from a model number, not from James Bond. If you have heard your child use this phrase, treat it seriously: it suggests exposure to knife-crime content online, or to peers who carry. Open a calm conversation — ask where they heard it, what they think it means, and who is talking about it. In the UK, carrying any folding knife with a blade over three inches, or any locking blade, in public without good reason is a criminal offence under the Criminal Justice Act 1988.

For ESL learners

'007 knife' is British street and prison slang for a small folding lock-knife; the number refers to a model code, not the spy character. The register is criminal underworld and journalism about youth violence — never neutral. In normal writing or speech use 'flick knife', 'lock knife' or 'folding knife'. A learner mistake is to assume any reference to '007' is a joke about James Bond; in this context it is not. Treat the term as semantically loaded: using it casually may mark you as either inside that subculture or naïve about it.

Why is this section here?

Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
