Folding knives that lock are also banned; I don't know why. I own a Buck Hunter knife, and I'm not allowed to step out of my home with that thing in my pocket. It would be really awkward to pull that thing out and extend the blade in the middle of an altercation. Perhaps the ban on lock-knives is that it's easier to stab someone with a lock-knife without cutting off your own fingers? As far as I'm aware, it's legal in the UK to carry a folding knife with a blade shorter than 3", as long as it doesn't lock. Fixed blades (e.g. a chef's knife) are prohibited for carry, unless you have a reason for carrying it (e.g. you just bought it).
