Chance of being searched are higher than most think.
Now we have random searches in train stations and the likes there's a very real risk of a completely sane and safe person carrying a locking blade being patted down and prosecuted.
Also if a crime happens NEAR you and the police get a report that someone matching your description is up to mischief, you can be stopped.
If you've got long hair, dark skin or any number of things that can get one of the legion of bad cops (the good ones aren't a problem) to single you out you're also far more likely to be stopped.
I disagree that the law isn't bad...
...I think it's blimmin terrible.
Most stabbings happen with screwdrivers and kitchen knives, and no law has ever managed to disarm the kind of scumbag who carries a knife with the intent of attacking someone.
Meanwhile, ordinary folk like us, like mums, dads and grandparents who pose no threat to anyone have to take the knife off our belt when we leave the woods, have to think about what tool to carry "just in case" we are searched and it serves absolutely NO purpose in terms of making society safer.
It's bleedin' MAD!
I hope things will change one day, but it won't likely be one day soon.
When (if?) the law allows, I'll be carrying a locking blade as EDC as they are far safer - until then I'm not running the risk.
Pity.
