I appreciate that a collector might want a pristine box - in which case the importance of the box would have superceded the knife in some respects. Long time collectors know the box is in the class of ephemera - something that is hard to preserve and usually uncared for. Most owners toss them. They aren't made well, don't ship well, and aren't made of any materials disposed toward archival quality.
Here's the thing - I get the same stuff handing out parts over the counter. The goal is to repair the car, and you can tell really quick where the priorities are with some folks. They check the part over, might ask about warranty, if all is good, they pay and they are gone - to fix the car.
Those that ask "can I have one in a better box" aren't concerned about getting the car running. Their mechanic is. There's the line - if the merchandise is going to be used, the box doesn't mean squat. If it's about presentation, it's all about image.
Hence - if it's for collection, image is important, if you are taking it outdoors to chop wood and dress out game, then the quality of the cardboard box isn't worth the time to write about it.
I don't see a middle ground on this - knives that have seen use outdoors will need sharpening, and a used re-edged knife doesn't get pricier because the box was thrown in. The market could care less. It only makes a difference if it qualifies for New In Box. And it better be. Those buyers are demanding.
Like what was said - the box hit the trash can. The post should have, too.
