I would think it is a promotional piece for Colt Fire arms , probably European do to North American knife laws etc . I've seen a Victorinox Swiss Army that also cared the Mauser Logo on the blade in a similar way .
Eickhorn made these for Colt if my memory serves at 90s.
The blade is usually etched CSAR Tool (Search and Rescue Tool).
I have looking these for long time but never found one from europe..
