10 things you’ve had and used the longest

There was this book from the 70s or something, bemoaning our throw away society. It made the case that our attachment to personal items gave us a sense of continuity that we need. Some generations inherited clothing, some inherited the crockery and cutlery. The book is "Future Shock" by Alvin Toffler. 

So in this spirit, which are the things you have used the longest? Your grandmothers plates? The dustpan and brush you've had for 40 years? 

This is not a list of things you keep for sentimental reasons. You need to use them.
