My first Spyderco was Native and I bought it, just to try S30V for $40. It out cut all knives, which I had at that point, including BM551 and 520. Later I wanted a gents knife and somebody recommended Kopa to me. I fall in love at first sight and now, six Kopas later I still think it is one of the most beautiful production knives.
Than there were Adventura, full size Persian (actually I have four of them), Dodo, Lil Temp, Caly3, Delica4 and they are not just excellent users, I love their appearance. I feel something really magic about Dodo.
I do not have that many knives, made by other brands. I sold couple BMs a while ago, gave away couple other knives. Why would I need them? All of them have the same classic look and not enough personality. Kershaws also look different, but it is not my cup of tea.
