Type of good that can be owned but not consumed when used
As I understand it, the best way to answer your question is to translate your description in to the language of economics and to understand the way that economists talk about these things.

To put this in to the language of economics, these would likely be "durable goods" with very low rates of depreciation. "Capital goods" (or just, capital) are a type of durable good. It is usually assumed that all durable good depreciate at least at some positive rate. This isn't a terrible assumption as, in your example, a hammer might rust over time---even if that time period is very, very long.
