Sometimes I will use something and realize I’ve owned it forever. It’s a nice change in our throwaway reality. I think my personal record is a bicycle multi-tool I got for one of my first bikes, ~25 years ago. Still have it, still use it. When it comes to electronic devices I have a Panasonic mini Hi-Fi from ~2005. Never felt like changing it.
What’s your record?
Also a knife for me. Have a chefs knife from when my ex worked in food service. Doesn’t hold an edge but very sharpenable (it was from the knife service) bought for $14 in 1990, have used daily since then. Plastic handle, too. But it’s survived longer than anything but my iron skillets. Which I also use most days.
