It's hard to really remember what sparked my interest in pocket knives. I was maybe 4 or 5 and my grandmother tried to give my sister and I a couple of a jack knives she had bought from the dollar store. They certainly weren't anything special, but I was instantly fascinated with them. I did kind of like the "weapon" aspect of some knives, but for the most part I just really liked the gadgety aspect of them. My father didn't let us keep the knives my grandmother got for us, but then a couple of months later after I said I wanted a swiss army knife ( some of my friends that were in the boy scouts had shown theirs off to me ) he bought me a little key-chain Victoronix that was on sale at a drug-store checkout line. That was my very first pocket knife and I just kept collecting more and more over the years. Of course being a kid I didn't have any clue of a really good knife, so half the swiss army knives I ever had were from the dollar store.
When I was 10 or so I was into coin collecting and the store I bought those from also had a lot of knives in the display case--artsy wall-hanger stuff. I saw some balisongs and thought they were the coolest thing I'd ever seen and had to have one... Bought one for $10 and learned how to sharpen with that one, as well as another swiss army knife I had gotten about that time--I don't remember which brand it was, but it was as a nice one, it took a razor edge. I remember the first time I saw Crocodile Dundee shave with his bowie knife I grabbed my swiss army knife and the Lansky kit I use to have at that time and saw if I could shave my arm hair and was amazed a knife could actually do that. Had a couple of other knives around that time but mostly display-case and gas-station special type stuff, some of them weren't bad knives--I got my first cut that needed stitches using one I'd sharpened withe Lansky to whittle.
My grandpa on my dad's side use to give me a couple of pocket knives when he'd come by too. Mostly cheap stuff, but he also gave me a couple of schrades that I really liked. Two Old Timers, one a dog-leg jack and another one I haven't found the model of, and a Uncle Henry stockman. I still have one of the Old Timers and the Uncle Henry. I remember the Old Timers were the first knives I'd seen with a real carbon edge and I remember thinking, "Oh, these have that old timey look." Apparently he used them to castrate pigs, so they were razor sharp when I got them and well sharpened... The dog-leg jack had a clip-point blade that was sharpened so much it looked more like a hawkbill.
Sometime around that time I also got my Buck 119 that I still have. That was my first fixed blade and I think my first super high quality knife, and at the time it was certainly the most I'd ever spent on one. It has held up great over the years and that was definitely a decade or more ago. I also got my first liner lock around this time which was a Buck Odyssey, but I lost it when I was a teenager... Used that one for a really long time.
I still liked knives but mostly just bought gas-station specials and disposable ones since I had all the quality knives I needed, but then a year ago or more I decided I needed to take up some old hobbies and got into sharpening and wanted to get a "premium" knife.
