Car makers design seat belts to lock in a car crash. It’s the safety feature that keeps you in your seat! If the buckle has also jammed, how are you getting out? If the crash has jammed your doors and you can’t roll down your windows, how will you escape? This specially designed hammer will smash your windows, and the recessed razor blade will slice your seat belt without danger of accidentally cutting yourself.
Small children in car seats? After a serious crash their car seat acts as their back board, so remove the entire car seat with your child still harnessed in. Use the seat belt cutter to cut the seat belt or UAS strap that has their seat secured to the vehicle.
