Editor's Pick: It's small enough to fit in your car door pocket without taking up space—about the size of two fingers. But in an emergency, it can make a huge difference. The tungsten steel tip is spring-loaded to break a side window with a single strike. The blade on the other end is hidden inside the housing and can cut a seatbelt one-handed. We recommend keeping one in every car. In case of flooding or a rollover, it could give you a few precious seconds to escape.
