I suppose I've been lucky. I haven't felt true regret yet. I haven't bought a cheap knife since I was a kid, and I didn't know any better then, so it never bothered me. I've had nothing but good luck for about 15 years now. Spyderco, Benchmade, Blackjack, Camillus, Ka-Bar, and Ontario have all been good to me. Plus, I usually wait until an outrageous deal pops up before I buy, so 95% of the knives in my collection were purchased below half retail price. I did pick up some AUS-6 SS Delicas for like $20 from a place that was going out of business. I gave them away as gifts to non-knife people.
