I have a Stanley mug, bought it in 96 when I was working in construction. It’s been kicked off scaffolding more times than I can count.

Used so much that the green started coming off ten+ years ago. So I sanded it off and it now has a brushed stainless look.

The lip cover has been gone for at least 15 years, worked well when it was there though. The mug is far too big to fit in any cup holder and has been tossed around mercilessly in every truck I have ever owned without spilling a drop up until the day it broke off.

The lid has chew marks where sharp puppy teeth of my long dead forever friend had himself a munch.

I can’t see ever replacing it and I don’t see it ever breaking to the point I’ll need to.

I also have a knife in the running that would fit the question.
