My post man brought me a 1989 2 3/4" Böker Stockman. Supposedly 1 of 500.

Never used, sharpend or carried but no box.
I have 3 questions for you guys.
1) On a value point of view, is this knife valuable enough to trade it for a nice 2001 Case in the same condition?
2) The seller said it was 1 of 500. How could I find out if that is correct?
3) If it is really 1 of 500 & I didn't trade it, would it be stupid to use it as an EDC? I LOVE the size & I'm sure it would make a nice EDC but as a inexperienced knifer, I don't know if it would be a mistake that I might regret ten years from now. Don't want to look back and think "Man was I stupid for useing that Böker"

or something along those lines.
Thanks for your thoughts & input & Thanks for looking!
