i did have a butterfly knife, but after going over the canadian border, they asked if i had mace, firearms, or knifes in the car and i said no not thinking, then she sent us to immigration where i was waiting to go to jail once they searched my car, but fortunately they just did background checks on us and let me go without having to get the vehicle searched. got over the boarder and ditched the butterfly knife, didnt need it around anyway...
