Saw this thing at the safety expo we went to over the weekend. http://www.munioselfdefense.com/ It's like a plastic baton/knife thing. Supposedly the guy who invented it is a self defense instructor They got for $12.50 with tons of designs (prints) to choose from. Or, for $25 you can take a one hour class that includes a Munio to keep. Curious what you guys think? Kirk, ever heard of this thing or this guy?
