carrying a knife is not illegal - yet.
But having a LOCK knife in a public place is a prosecutable offence. And the definition of 'a public place' is vague bordering on conprehensive.
So a three inch long, wide bladed lock knife is tantamount to carrying a firearm in the current eyes of the law.
pic below illustrates the difference between my old edc and my new one
As you can see the old one is a tad conspicuous - great little knife cost $7 from walmart 3 years ago and has probably been used nearly every day since.
Wouldn't swap it for one 10 times the price
But I do have a tendency to whip it out with a flourish and a fast click on opening lol (david morningstar and slingbagder can testify to this, they both jumped lol). I can do the same with the new one and nobody bats an eyelid.
The new one is still technically illegal 'cause it's a lock knife - but the odds of anyone being worried enough to call the police is pretty much zero. And yes such sad people do exist.
Guy got done in burton recently for simply taking a knife out of his pocket and putting it back. Nobody anywhere near him, he wasn't threatening anyone probably just rearranging his pocket, but some arsehole monitoring a cctv camera spotted him and he was prosecuted.
I don't intend to take the risk.
Sad, but unfortunately it's the law now.
I still have my little swiss army knife and the gerber, but I very rarely use the blades on those.
