I've always liked knives, but as a kid, it's not like you can afford to have a collection. I'd use a knife 'til it was broken, lost, or given away, then I'd find another.
First quality knives were from A. G. Russell's store in Rogers, AR. At that point, I was able to keep track of knives a little better, and when I finally graduated college, and had a "real" job, I've been accumulating at a higher rate.
Really, the first quality knives that began my accumulation problem was a Benchmade 875 Sentinel (Elishewitz design) and a BM 3000 Auto (Pardue design) that I bought in '98. @ $75 each, I never imagined spending more than that.
