I am not sure I have much stuff that will last an actual life time. Maybe various optics like binoculars, etc. But that is rather niche. For stuff that most everyone can use, I would mention cast iron cookware. I have cast iron skillets and pots that I have used for over two decades that I expect to last me many years still. And I use them all the time. The brand name is not very important although you probably want to avoid the very cheapest. Next, I would say good quality knives. Both for use in the kitchen as well as in the forest, on hikes, etc. For Chef's knives, I think F. Dick makes decent ones that last very long for home use. And for forest use, I would recommend LionSteel.
