Right now I have a carpet knife, a big Buck knife, a cheapo 3 dollar pocket knife, an old fashioned Winchester pocketknife, and a folding multi-tool with a knife and pliers, etc., built in, in my pockets. Carry them every day...except Sunday when I only carry the pocketknives. If I had been there with my truck there would have been a cordless Sawzall and a battery powered chain saw, too. Even if you don’t have a knife, break a bottle or morrow and use the glass to cut. Don’t they have ANY rednecks out there?
The witness who tried to rescue her seemed to indicate the young lady was additionally pinned somehow... :-(
Still, a multi-tool and a good cutter of some sort are a very good idea to keep in one’s vehicle.
