Back-door brass knuckles?

This tool seems singularly useless for it’s stated roles. Maybe it would be useful for something else…

It’s unclear how thick that striking surface is.

    As a glove-compartment multitool it might be useful. But the lack of a lever arm on the hammer makes it very inefficient.
