Cast iron frying pans. The old kind with the machined (not just raw sand cast) inside bottom. You can destroy them by heating them red hot and then quenching, or dropping onto concrete (I know of both being done). Barring that, will last lifetimes.
Any decent kitchen knives - don't have to be showy brands - my favourite one is a Cuisinart. But if the handles hold up they're worth sharpening indefinitely.
Any kitchen stuff made out of tempered glass - casserole dishes and the now collectible coloured glass Pyrex bowls. Again you can destroy those by shattering them, but if you don't, they'll outlast you.
