Consider this formula:
(grossly harsh and generalizing)
If you cringe at scratches and spend an excessive time polishing or sharpening or cleaning - you are at heart a collector/dealer. You are keeping it "ready" in case you should ever need to show it off or sell it (the basic definition of collecting and dealing).
If you brag about your scratches or they bring back fond memories - you are at heart a user. Your knife is dear to you and you'll probably never sell it.
Nothing wrong either of these camps of thought.
In fact, I believe it may even be a case-by-case basis.
Here's a sampling:
My YCS was the last one made last year and was not, ahem, up to spec. Because of that, it became an immediate user and has seen some serious usage.
AK Bowie - again a reject. (anybody sense a pattern here?) I plan on going so far as to put a convex edge on it and reshape the handle. Definite user (once it's done

)
Pen Knife - well, you all should know about that one by now...
The others get rotated in service as choppers or kitchen duty. I don't hesitate to pull any of them out. Nor does it bother me to get scratches. Sometimes it takes a little courage to put that first scratch on it, but I usually end up forgetting about that stuff after a while anyway. Besides, if anything happens to it, I'm confident enough in my shop skills to know I can put it back together (decently). Maybe that's why I like rejects - fits in with all my other "projects".
