My classics are a Victorinox Hunter and USGI steel canteen cup. They are about 30 years old and still in use. My Silva compass is only around 20 years old. I have new canteens, but the cover is original and needs to be tossed for an upgrade very soon.

Of those three, the most used is the cup. It's blackened, has a little ding in it and is old, but those are character marks to me. I still use it every camping trip. But since I don't use the cover, it usually resides in the camp cooking box.
