Fair warning, when I say that this is a DIY project, I don't recommend that you recreate this electric Ninja Sword yourself.
Not only is this shocking death dealer a double bladed ninja sword, but it's combined with a taser to create a frightening weapon. The creation from YouTube user GreekGadgetGuru can not only cut through steel, but delivers a crazy 8 million volt charge at the same time. When looking at this thing, I have to wonder what the point of the insane voltage is when the victim is likely being hacked up at the same time, aside from a fear factor. In a clever (read: incredibly necessary) touch, the wielder of the electric ninja sword must wear a special contact glove so that the charge doesn't shock the user.
There's nothing like an electric ninja weapon to create a little shock and awe amongst enemies.
