As far as i know canada has no blade length limit, am i correct? a Friend of mine says there is a 4" limit, which would be impossible since you can go buy something 3 times that long in pretty much any knife/outdoors store. I know anything that can be opened automatically or with gravity is a no no. But as far as fixed blades are concerned i thought anyhting goes, i know double edges are legal. So feel free to tell me im wrong, if i am, and provide links if possible. Thanks guys!
