Honestly, I don't think of myself as a collector. I just see a knife that jumps out and grabs me and I think, "Maybe this could be my new EDC." or "This one I'll carry hiking and camping."
But after "trading up" for several years I look at my knife box and find that I DO have a bit of a collection.
I buy knives to use, but that doesn't necessarily mean that's what happens after I get them... for very long! <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
