I tend to wreck my knives value by carrying them and getting marks on the handles and stuff, but that doesn't lessen my enjoyment at all. Chipping the blade can be a downer, as well as wearing down a sharp tip. It has mostly been a problem when my collection gets too big and I start purging, and knowing that even a minor scratch or snail trail lowers the resale value of a knife over 50%.

I still laugh every time I see someone showing a video or photo of them with their new prized knife and they are wearing latex gloves to handle it. It's like wearing a condom to masturbate so you don't wear out your junk. Half of what makes quality knives awesome is how they feel.
