Ever ordered car parts and in order to get free shipping you need just a few $, but don't want to add more than the cost of the shipping you're trying to avoid?
This safety hammer was one of those cart add-on's.
I think it's a good tool to have in case you're trapped in the car. I hope I never need to use it for its intended purpose: breaking glass on one end and cutting seatbelts on the other. Clears the phone no problem and even glows in case you need to find it at night.
Not a flashy mod, I know
