Everyone has their own idea of what do to with their money and possessions. For me: I have a couple of knives that I dont use. I have had many that I bought and later sold that have never been used. Mostly Busse and Microtechs but really have bought very few with the specific idea of keeping as safe queens and never use. I have used $400+ knives and not worried about it but I find that I can get a perfectly good, dependable, high quality user blade for way less money and have moved in that direction. I recently sold almost all of my safe queens. Lots of those come with a mirror or highly flashy finish which I don't care for in a user and the handle choices on mine, while very attractive, were not my first choice for a user.
Though they are not rare nor anywhere near the high end of the knife price range, I just acquired a Swamp Waki and a LE Ratmandu which I promptly unwrapped took out in the yard and started cutting things with. I forced a patina on the LE which I guess immediately ruined the collector value and made it a user. Really there is little that bugs me more than to see a picture "my favorite woodsie or my all time SHTF blade" posted without a scratch on the thing. I vote use em! Those campouts, hikes, etc: with gear being utilized are among the threads I most enjoy viewing on this forum.
