Yes I do, and I look at it just about everyday and still use it some, though I don't EDC is, as the sheath closure flap has worn so thin I'm afraid to lose it. It sits on my desk in its sheath on top of my Sharpmaker, never out of arm's reach.
It's a 1973 model Buck 110 that my grandfather gave me during the summer of 1987 when I was six years old. When I was little both my parents worked days and I'd spend summer days with either my dad's parents or my mom's mother. My grandfather's (dad's side) brother had a pond that was fed from a fairly large stream and freshly stocked with catfish, bass and a few others every year. My grandpa and I would go fishing every chance we'd get. One day, he said "a good fisherman always needs a good sharp knife," and he handed me this huge (for a six year old) brown leather sheath. At the time the knife was 14 years old, so the sheath showed some signs of wear, but the knife inside was perfect.
Over that summer, I wasn't allowed to take the knife home, and I coudl only use it when grandpa and I were fishing or working in his wood shop. He taught me to respect the knife and not to rely on the lock (even though it has never failed and locks as solidly as it did in 1973). He also taught me how to keep it sharp, no easy task for a six year old with 440C. When he was sure that I knew what I was doing, he let me take it home.
It's still like a razor. Since I got my Sharpmaker, it's the only knife that I still use benchstones on. Just doesn't seem right to sharpen it any other way. I've got a two dot 110 that I'm planning on sending in to Buck to get a new blade and sheath, and I'd first thought about getting a new sheath for the 73, but have since decided against it. I think this knife should stay in its original home as long as possible.
To this day he asks me abuot that knife. Last time I saw him a few months ago I had it on my belt just so he could see it. He's really an amazing man, WW2 vet served in Germany and the Pacific, is nearing 90 and still hunts and fishes every chance he gets. His only fault... he got me addicted to knives.
I don't remember the first knife I bought. I was taught my my dad and grandpa to only look for quality. It costs a little more but it's worth it. If you can't afford it, save some money and then get it. The only knock-offs I've ever bought were just for testing purposes... to see what it took to destroy a $5 knife (not a lot). I've bought a lot of Buck 110s, Kershaws, Camillus and Victorinox. I'm sure one of the first I bought for myself was some sort of SAK, and interestingly enough, the SAK bug has bitten me lately and I can't seem to get enough of them.
