Knives that are prohibited in Canada (for no good reason)

The videos talks about the following types of knives which are illegal in Canada, and why these prohibitions make little sense: - Automatic knives / switchblades - Centrifugal knives (e.g. flick knives, balisongs) - Gravity knives (e.g. a certain paratrooper knife) - Finger rings with blades - Push daggers - Blades concealed in everyday items with a length of less than 30 cm - Knives with brass knuckles / knuckle duster handle (e.g. trench knife) Source:
