It is hard to say exactly when I became hooked on Spydercos. My first Spydie was a Pacific Salt SE and although I was awe struck by it, it was still early in my knife gathering days. I was still bouncing around from brand to brand for a while.
I bought a Caly 3.5 a couple of years ago and it got lost in the shuffle for a while before becoming my light duty weekend warrior and eventually becoming my edc work knife.
Last fall though, when I purchased a couple of Militaries, I realized Spyderco was my brand of choice and I had this feeling that I was done. I have mostly just been hanging around the last six months or so out of habit.
I am usually not too much of a brand whore. My golf bag is loaded with an assortment of different brands, as is my a/v equipment and fishing gear etc. But after all is said and done, and after all the different knives I have bought, Spyderco claims the top three spots in the lineup. Four and five belong to other brands and only get used occasionally.
