If you are worried about the authenticity of the knife we would have to have pics of everything first.
If you are just wondering about the actual knife itself, I mean, it's probably the best factory Bugout you can get. I still have my original Bugout, never really carry it though. Never really fell in love with it like many people did, even after Flytanium scales. But the one you got is a definite upgrade over most other factory Bug's.
Benchmade as a company make a good product, good QC, and good warranty. They will take care of you if you ever have an issue.
