The title says it. When you look at your current pocket dump, what is the oldest piece of gear in there? Mine is weird. Albeit the fact that I do carry things that are well crafted and meant to last an entire lifetime, I also tend to swap out stuff and in my current carry, quite a few things are close to new. My oldest piece of gear is, of all things, the one thing that was never meant to last a lifetime. It's my smartphone, a OnePlus 3 which has been with me for more than three years now. (since it's the host of the only camera I own, I took a random pic from the internet.) Mine looks like new, though. I've always carried it in a case and had the screen protected. No scratches except a few around the USB port.
