Multifunction

Multifunction is the sort of label that promises range before it says what the thing actually does. By our assessment, that makes it useful only in the loosest sense: it signals flexibility, but not the specific task, material, or format a buyer would need to compare. The upside is broad applicability, since a multifunction product usually tries to cover several jobs in one item. The downside is the same broadness, because anything that does many things can do each of them less well than a dedicated tool. In practice, that means a person still has to read past the title to find the real use, and the name on its own gives almost no help.
