Yup. That’s one of the great things about the OXO stuff we have. I have a new vegetable peeler, that replaced one we had for over a decade. It’s basically, exactly the same one. I suspect the parts would be interchangeable.

I think that Apple’s Snow Leopard MacOS release was almost identical, in surface features, to its predecessor, but is considered one of their best releases, ever, because it fixed so many bugs, and improved a lot of important functionality. Internally, it also established a technical fabric for the new architecture, but that wasn’t visible to users.
