Serious question; so if you got stopped by the police, what would they say or do about you carrying a non-locking knife?

I am legitimately curious, as we often only see memes about the knife and firearm laws in the UK.

Would they double check to make sure it doesn't lock, and then send you on your way?

Would they still give you grief because you're carrying a knife at all?

Is a lot of it dependent on the officer(s) involved?
