In my opinion, calling a knife in that condition LNIB, while not quite the stretch as calling it Mint, is still not an accurate description. There is nothing "like new" about a scratched up pocket clip, frame, and other clear signs of being carried or used. If it came from a dealer in that condition it'd be sent back.
I detest single word descriptions or acronyms to describe condition. They are way too subjective to be meaningful. If one simply says mint, NIB, or LNIB, it better be in the condition that it came from the dealer or factory. And a solid specimen at that.
