Everybody has their own limits of what price range they will carry, also everybody will look differently at owning an item that you don't use.
Years ago I collected custom hunting knives, with no intention of ever using any of them. In the time since then I don't think I've even had an occasion to go hunting so no possibility of even using them, and I still have them. I like to look at the style and the craftmanship. So it is OK to own something that you don't use.
I also buy a lot of folding knives, but I buy them to actually carry and use. I have upper and lower price limits as to what I feel comfortable carrying. I think if a person buys something to use then they have to decide if they are going to use it or sell it. If you are going to keep it and it isn't a very rare item that could be significantly devalued by a little use, then go ahead and use it a little. Just take care of it. As long as you don't scrape mud off of your boots with it, or cut electrical wire, or pry out nails, you can use a knife a little bit and not change it significantly.
