Safety is always the first rule that needs to be followed in driving. For you and passengers' safety, place a safety hammer in your car! No one can predict what will happen in the next second. With these emergency hammers in your car, set you free from a traffic accident (we hope it never will happen!).
Using tips: If involved in an accident that the vehicle's windows and seat belts cannot be opened, cut the seat belts with the razor blade; then break a side window with the sharp tips which are fixed on the hammerhead.
