I couldn't find anything similar on Gerber's site or bladehq so I imagine it's discontinued, I posted a photo over on Reddit's knifeclub forum, maybe someone there will know.
"It’s called the Gerber Ridge. It’s a money clip knife. They are discontinued as far as I can tell, but they were about $25 new. Used they aren’t really worth anything. $5-$10 maybe if you convince someone to buy it."
