Butterfly Knives

Dude I Want That

Another weapon that gained popularity during the height of martial arts was the butterfly knife, which was also commonly used during the 1970s. Because it was so easy to conceal, it eventually became known as something to use in order to maim or kill someone. Its design is both foldable, but quick to open to reveal the incredibly sharp knife without anyone even seeing it at first. Because of this, they are banned in a number of states while having a number of very strict rules in others.
