I have a couple.
Pretty much anything store bought is a user, destined to be lost, stolen, confiscated, or buried with the body. Just kidding on the last one.
I don't have money for anything custom unless I make it. And if I made one, I can make a better one. So not that category either.
Stuff I'll never sell is special due to conditions of acquiring them, or sentimental association of who I acquired them from. For example:
- My Mother carried a small, Imperial spear-point friction folder with a stainless sheet metal handle in her purse. I remember, on a cross-country road trip in our '69 Econoline PopTop Camper, eating pears cut in slices by that knife. It's actually quite a nice knife: slim, sharp, useful shape.
- My Dad always carried a boyscout knife in his pocket. He liked that it had multiple tools, he liked to tinker. Nothing special, but I have it. He'd have gone ape over a Leatherman if it had come out 20 years earlier.
- A really beat down Scandi from my Grandfather. He built a cabin in Western Maryland on Deep Creek Lake, which was my favorite place to be in the summer as a kid, and this was in the old cabin tossed in a bucket with some old construction tools. It had paint spatters all over, the stacked leather handle was mildewed, and the blade was rusty and had been sharpened inexpertly on the flat edge of a grinding wheel. But with clean-up and care, I love it deeply.
- Some knives from my travels. My favorite one is from Mongolia, and is certainly not antique. Antique men's knives frequently came as big and little sets which included chopsticks.... sort of Silk-Road era Hobo knives. I wanted one, but those brought big bucks.
- And of course, the first knife I ever made. Goes without saying.
