authenticity check?

hi all, first time posting here so apologies if I'm breaking any rules I might've missed. I'm looking to pick up this microtech secondhand and was wondering if someone could help to verify the authenticity? I attempted to post in the microtech sub but was immediately removed so I'm still waiting to hear back on that. the only obvious differences I can spot is the printing on the pocket clip but it looks like that is just worn down and I'm not sure how easily those wear so maybe it could be real? the owner also said he has the original box and warranty card if that helps to verify anything, although I couldn't find a serial number checker anywhere on microtech. please let me know what you guys think and if there's anything else I could provide that would help, thanks!
