I already had one. But on the last sale, I bought three more. The wife found them and said, "What the **** is this?! Planning a party or something?" I told her "One for your car, and one for each of the kids cars. I already have mine." I think these are the perfect keep-it-handy-you-never-know-when-you-might-need-it knife. Stash it in the car emergency kit.
