Ha ha aha ha ha . . . wait, was that serious?
From past experience, don't be surprised if a law enforcement professional (police or border patrol) in Canada randomly decides that if, on their seventeenth try they're able to finally wrist flick a folder open, that it's suddenly a "deadly weapon" or a fearsome "gravity knife".
I ship knives to Canada occasionally and they've declared 1/3 of all Benchmades I've sent there deadly assault weapons of mass destruction (this despite my intentionally tightening the pivots to the point that they can barely be opened). Admittedly, I've only shipped three Benchmade knives there, though.
I've seen the same silliness in the US, though. I once saw a Wisconsin state trooper flail around so hard I think he probably needed rotator cuff surgery afterwards before finally getting a guy's knife to open, and then giving him the "Say, this is a very nice, er, illegal knife. I'm going to have to take this for myself, er, confiscate it . . . or I guess I could charge you with carrying a deadly weapon if that's your preference".
