The CRKT Extrik-8-R Rescue Tool ($13) was made for emergency professionals, but it could also make a great go-to emergency tool for the rest of us. The Extrik-8-R features large finger holes and grip grooves so you can operate it even with thick gloves, an oxygen bottle wrench, standard and Philips screwdriver tips, a seatbelt cutter, and an orange reflector fob. Overall size is 4.17 inches.
