I didn't like the way Spyderco knives looked, but a local gun shop was selling off their old stock and I bought a Viele and a Walker (still don't love most of them aesthetically, but can't complain about quality and performance!). I started carrying them and using them a lot, next came a Paramilitary, Endura 3, Native III, Centofante 3; which were quickly followed by a few dozen more.
I still don't find them pretty (with the exception of the small Persian and the Loom Chinese folder), but they are just awesome tools.
