That's probably because "NIB" and "perfect lockup / centering / etc." aren't the same thing. I appreciate they should be and that folks see them as such.If I've stated something is NIB, and someone asks "What is the condition?", I probably wouldn't find that a very helpful question. If they have specific questions - "Is it centered?" "What's the lock-up?" etc - I'm fine with that. I do find it strange that a number of people have said something to the effect of "It arrived in much better condition than I expected" for something that I've already stated as NIB.
I've absolutely gotten brand new knives from a dealer that had F&F issues out of the box.
