That's a potential danger, however, if you get in a bar fight with someone carrying this ridiculous knife/gun contraption. As you can see in the above video, bullets are loaded into the handle and then fired out in the direction the blade is pointing, catching any potential knife fight opponents really, really off guard. Not that getting in a fight with someone with a regular knife or regular gun would be a good idea, but if you see someone with one of these, stay on their good side.
