This car kit should be at everyone's fingertips. With this tool, you can literally save a person's life if they ever find themselves in an overturned, sinking or burning car. An emergency hammer gives you the ability to cut the seat belt and break glass so you can quickly get out of a dangerous situation.  On one end of each tool is a sharp blade that easily cuts through a stuck seat belt. And on the other is a steel-pointed head that can break car glass if you need to escape and the doors are jammed. These tools also have reflective tape on them, so the hammers are visible even in low light. Plus, the tool lead just under 5 ounces, which is enough to swing with force to break glass.
