I think this is an emergency tool. Glass punch/seatbelt cutter.
The image is a little blurry but it appears to be an auto emergency tool. But usefulness of said tool appears to be lacking. If you are frantic, do you really think you will have the patience to get the belt in that tiny cutter at the bottom. Also the glass break seams to be more of a hammer head (flat) instead of the typical spiked. And then if that tool was to slip as your were banging on the glass, would you cut yourself on the bottom? I'm not even sure what those middle saw ridges are. Yes it might be an auto emergency tool, but it also might be more useful in the trash. It's up to you what you want to do with it.
