What's with Britain and knife crime?

Exactly how big of a knife does it have to be before it becomes a problem over there anyway? I know quite a few people in this area myself included who carry a pocket knife at all times just as a general purpose tool. And I can safely say in my oh 15 years of doing so I've used it to cut packaging, eat meals, and pry stuff open but never to shank anyone. That seems to be the common experience with the matter as well.

Never mind the problem of trying to get rid of everything you could possible kill someone with being aggressively ineffective. At least until you start confiscating peoples hands and then there'll still by some psycho who becomes skilled at killing with his stumps alone.

Jam it back in, in the dark.
