So an item's ability to be used in combat so as to overcome any specific resistance is certainly a "function" in the ordinary sense of that word. Thus whenever the sword "functions as a normal (not magic) blade" then it lacks the functions that are associated specifically with magic ones, including the function you are asking about.
