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?
A well maintained bike has incredible durability. I don't use this one off road any more because I bought a suspended machine fifteen years ago but I can't bear to part with my old friend. With a little imagination they can be modified for a new purpose. It's a fun way for kids to learn basic skills.
