For me it was something akin to "destiny" lol.
Growing up my family did a lot of camping and travel, so I naturally decided (as a 4 yr old visiting Mexico) that I needed a machete; my dad said I had to keep track of my Swiss army knife for 12 consecutive months before he'd even consider it, so as it happens I was 7 when he got my first "big" knife - 3" camp knife (no name).
The years added (& with it my collection); I finally got my machete when I turned 16 in the Philippines!
At 20 teaching Wilderness Survival at Summer Camp I was introduced to the KaBar my USMC cousin had told me so much of, but I didn't "love" the grip. I started looking for other quality camp knives and found ESEE, but before I could save enough I got married, and at the reception my best friend said "MY wife says I'm breaking wedding rules by giving you this, but... I remember when we were kids knocking around the Michigan Forrest each summer you'd always bring me souvenir knives from your latest trip, and I hear you're back into "survival stuff" so here's some good old AMERICAN steel!" At which point I opened the gift-wrap to find a BK7. It was love at first sight! Lol
I've since carried it in a thigh rig hiking in OR, on a Shoulder rig in the Balkans, and now with a Florida CCW I plan to carry it IWB as soon as I make a Kydex sheath... It's a carry-worthy knife!
Looking for DIY Micarta scales brought me to this forum, and a Google Image Search included a BK7 Bayonet by Murphnuge and TMHunt, and every cool BK7 mod kept bringing me back to this forum, and when I realized that my "custom" EDC knife design looked almost EXACTLY like a BK10 with a finger-loop I decided I should join, and when I found this thread I thought "what the hell, I'll do my introductory post here" and four hours and countless words later, all I've said really just boils down to "destiny". lol
Sorry to drag it out, I'll try to keep future posts short (and only write when I'm awake, lol)
