A lot of mine are gone and/or going to new homes.
Since childhood, I've had a hard time dealing with OCD and one character trait of that is packratting. I've finally come to grips with it, probably just because I'm older and a lot more honest about the stuff going on in my noggin.

It's been a lot easier to 'let go' of various things I've held on to, and my knives were one area of interest where I went way overboard.
It's been hard, but refreshing to let a lot of this stuff go. I am keeping my heirlooms, those given to me, and of course, my Stockman patterns. Ain't givin' those up. But a lot of the knives I don't use (at least 50-60 at last count) are going to new homes, either sold or as gifts, where they'll get some good use.
I love Sal's (Glesser) quote with regard to Spydercos:
" . . . Spydercos are hungry and like to eat. As mentioned, open, close, cut, clean, oil, cut, cut, cut... To a Spyderco, that is living."
I think that would apply to most knives, at least the ones I have.
Great thread - good to hear others' philosophy on this topic. (I know I'm not the only one 'cutting the cord' with my babies.
