Fun to think about, bleu! I bought a jacket in 1980, for my first trip out of North America and have used it every time since! It even went to Borneo! I have a cast iron skillet which my grandmother owned. It's GOT to be over a hundred years old...still well-seasoned and still non-stick!
Looking forward to seeing some other responses.
I used to have an old knife, like an American made Swiss knife from 1963 when I was a kI'd. My brother, in the army at the time gave it to me. I retired it and gave it to my one son.
I still have a jeans jacket that I wore to Woodstock in 1969...I was 15...it still fits!
I also have a rice warmer that was passed down to me from my Japanese grandparents...it is probably over 100 years old...It is wooden and I only use it for special family dinners...
The oldest part of my house goes back to around 1840, I have tshirts from the seventies I still occasionally wear and a pair of jeans from around then that have just been fetched out of the suitcase storage. I have old 78 records I still listen to sometimes. Quite a bit of my furniture and ornaments around the house are from the 18 and 19 century I have garden tools and work tools that my great great grandfather and each generation since have used .. probably a lot of other old stuff around that I still use and never wonder about their age.f
I use my grandmother's cedar chest. I've had it for 31 years. I still have a game that I bought in 1996 for my son at work. Both are still in perfect condition. My car is a 2006 Hyundai, not perfect but only appearance flaws.
I have a tendency to use things until they wear out.

easiest answer is coffee cups...I have coffee cups from the 70's...still use, for brushes and knives(painting)...
I have a yoyo I stole from the mall of America 25-26 years ago, that has to be the oldest thing Ive personally acquired. FWIW I emailed the the store 2-3 years ago to return or pay for it as an example to my kids, no response even though their still in business.
