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?
My coffee mug. I have it for more than 30 years and still use it regularly, even if not on a daily basis. I have obtained others through various means over the years but still hung onto it all this while. It doesn't even have a chip or flaked off bits of it's design.
I also have a hole puncher that my dad used as a young man. It's probably close to 50 years or even more. It's all rusted up now and doesn't really see much use to be fair, but it still works for what it does.
