Probably back in 1997 or 1998, when I was about 9 years old, before I left for a canoe trip my parents gave me a fully serrated Spyderco Ladybug. Haven't seen it in years. Wish I could find that little lady. Although, I have a strong suspicion that one of my middle-school pals stole it.
2011 was when I got really hardcore into knives. Bought a Spyderco Manix2 lightweight and a CRKT Ultima. Shortly after that, I dropped a little over $300 on a Socom Delta and have since spent a lot more on knives than I am willing to admit.
