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?
All I’ve ever had to do is sharpen it. It was pretty tight when I first got it but it loosened up after a couple weeks. The joints on the Skeletool are also star bits rather than rivets so I could adjust it if need be.
