Mitch, the idea behind the belt cutter is that you may be hanging up side down, and lets face it, if you just flipped your ride falling on your own knife would really be the frosting on the cake.

No BS, True story. When I was in the Marines some guy coming back to base rolled his car, he wound up hanging upside down for quite a while before help arrived, when the firemen, cops, and paramedics started thrashing around, they found out a rattlesnake had crawled into the warm car, it got scared and bit the poor SOB who had been uninjured till then, just stuck.
