yeah, but they're banning knives.
No, they're not.
They have launched a knife amnesty. That's a different thing entirely.
An amnesty is a publicity stunt for politicians. The politican gets to stand beside a big pile of knives and say "look how much violent crime we've prevented".
Meanwhile, the public go about their business as usual. As Sparks pointed out, the number of knives that have been handed in is tiny.
It's rather like a gun buyback in the US, only slightly less moronic as the knives are not being bought with public money for this publicity stunt.
There are very few types of knives banned in the UK> from memory, modern (ie not antique) sword canes, butterfly knives, belt buckle knives and flickknives.
The other types are legal to own, legal to buy, and only illegal to carry if a: they were designed as weapons (not tools) and you don't have a good reason to be carrying them, or b: you intend to use it to commit a crime.
Yes the carrying of knives in public has been on the books for at least 20 years to my knowledge and yet I still have a Swiss Army knife and carry it routinely as do millions of other people.
Pocket knives with a blade of less than 3 inches (from memory) are not classed as weapons.
