When I was practicing jujitsu, our instructors were pretty unanimous that they would rather be robbed by someone with a gun than with a knife. Not that your odds are great against any weapons, but a gun only has one dangerous bit. The first time I was learning to disarm someone armed with a knife I was told “If you fight someone with a knife, you’re going to get cut, no question.”
