Not that at my age I'd be quick enough to remember or react in time to use them, but I always have a Spyderco Delica 4 clipped to my pants pocket. In my car, a Honey Badger serrated Claw folding knife in my center console, and an 8" plastic stabber (with a 3" triangular pointed end) in my door panel. In my trunk, a Morakniv 4" fixed blade sheath knife and a folding utility knife. In my wife's glove box is a CRKT M16-13ZLEK folding knife with a seat belt cutter and window breaking tip. She also has a plastic stabber in her door panel. For our rare walks, I take a Morakniv Eldris neck knife.
