Good point, Sunburst. I've often looked at all my knives and considered paring down to just a few. Then again, I have collected some because I like the handles and the execution of a pattern. I have some I mostly look at and enjoy the process. When I do think about carrying them I realize I already have several others in the same patterns I'm already carrying, so perhaps I should leave them up a little longer. I've done a few cuts with them, I always do. Therefore none are technically mint. Just very NIB! And, some don't pocket as well as others. I've also stated before that I think we collect these type things to help of remember, and perhaps fantasize a little over eras and lifestyles that we can't touch currently.
I started buying a few SAKs and some Old Timers from the Force Exchange when I was on a year tour in the Sinai with the MFO, just because I had to leave all my guns and stuff behind, and there was no place I could really go wondering around, due to rules and land mines. Handling the knives and carrying one or two reminded me and kept me connected.
Truth is, if I had a chance to live backwoods again, I'd probably have just a few steady working knives and maybe a purdy one or two I kept for looking at. Even then, I wouldn't want anything around I couldn't put to use if I wanted or needed too.
Perhaps the balance point is to have some nice ones we keep shiny and put away just to enjoy looking at and handling as we sit in our favorite chair, but with keep from becoming excessive about keeping them pristine for some future generation.
On generations I have to agree with Jackknife. Having something handed down that had been carried, used, and cherished by the former carrier would add more meaning to me. I wish I'd hung on to my Dad's (his birthday today, btw) Kissing Crane Congress a little longer and used it before passing it on to my son. It already had the handles smoothed by years of carry and the blades were less than 100%. I'd have liked to have partnered with it a while and added some more polish while reducing the blades a little more. I might not have meant more to my son, but I miss the time I could have been adding some legacy of my own to it.
Like everything else, the ideal lies somewhere in the middle.
