This multipurpose tool works as a emergency window breaker in case of being trapped inside vehicle.
Also works as a seatbelt cutter if trapped inside vehicle.
This tool is (well, will be) a lifesaver. And at this price, get multiples for you and friends. The tool itself is a compact multi-purpose tool.
I order from this company often. I liked the quality of this tool so much, I came back and ordered more.
