Most likely, Hagoromo used the sword to fight the Ten Tails, reshaping some of the landscape in the process. With all due respect, I disagree. Obito said Hagoromo used the sword to shape and that it can just as easily destroy. If he meant shape terrain in battle, then it would have meant the same as destroy.
