The "Rescue me" keychain is spelled Resqme, and according to the story I saw on Fox News, it's a serious emergency escape kit.   It's designed to help us out of a sinking car or help us out of one after a crash.   It is one of the featured items at the SEMA Show in Las Vegas.

This little bright-colored device features a cutting blade sharp enough to slice through seat belts and a spring-loaded spike capable of shattering a car window.  I haven't shopped for one yet, but Consumer Reports says you can supposedly find the Resqme at department, auto parts and even some convenience stores.    It comes in assorted bright colors and costs under $10.     

It's recommended that you use it either as a keychain, or simply mount it where the driver can have easy access to it in the case of a rollover.
