We travel almost everywhere we go in cars. But what if there is an emergency and you can't get your seat belt off? Even worse what if you get off your seat belt but need to break the window to get out of the car. I don't know about you, but I am not a muscle-bound guy who loves smashing things. That's why this tool is perfect to keep you safe in an emergency. Buy one for each seat your loved ones sit in and rest assured that you are prepared for any situation. In the event of an emergency, pull the tool away from the clip to reveal the blade. If the seat belt is jammed, cut the belt by hooking the blade over and slicing it across. To break the window, press the black head of the tool against the corner of the window and it will release the spring-loaded spike and shatter the glass. The tool does not work on car windshields. It is effective only against tempered glass commonly used inside windows. Keep away from children and do not press the black head of the tool against skin or anything that is breakable as the ball is released with force. Please note it does take a good amount of force to release the ball and may take a few presses to fully break the window.
