O, and a sorta cheapish folding knife came in the mail today that I ordered. Some Chinese made thing for Remington.
Looks ok for $20. 5" blade, with half of it serrated (so, good for cutting ropes, cords, lines and other binds); farm stuff (don't want to use a $150 knife for that work).
Probably a good knife to keep in the car in case of a crash and the seat belt becomes snagged or your shoes get wedged under the front panel if it's a decent crash, and you can't get your feet out without cutting the shoes off. You could break the tempered glass with it in the closed position too. I find it odd that lots of people that drive don't have something like this in their car (in addition to fire suppression devices and crowbars). But hey, I guess I'm a worrywart.
