ResQMe is one tool you’ll hope you never have to use – but if you do it could easily help save your life. Basically a pocket-sized spring-loaded LifeHammer, ResQMe can bust apart a car window just by being pressed against it. It’s also got a built in seat belt cutter to quickly cut a restrictive seat belt if necessary. Especially useful when the car ends up under water as power windows often get jammed and opening the door against the immense water pressure is apparently quite difficult.
Various colours available. Order one for yourself at Amazon to stash on a keychain or in the glove box – 10$.
