Welcome to Bladeforums.
That knife looks like a Gerber Aspect, but based on several characteristics, I suspect it to be a counterfeit.
Comparing it to one on a reputable site (Knifecenter), your knife has different types of screws, and the blade grind and logo placement are different. And I can't find any mention of Gerber producing the Aspect with a black blade. Also, the pocket clip looks different from every other one I see.
