Things like this have a certain appeal to some of us, not based on their usefulness,but more for the sheer cool of it. As a practical tool, no sane person could make a case for it...but that doesn't mean we wouldn't want one. If I had one, it would be in good company.(Peace-pipe tomahawk, boar spear, airsoft gun,etc.)And if lemmings and regulators get their panties in a bunch, so what.
