Nimue didn't have as much information about the Dagger as we do. Perhaps The Dark One didn't know yet she could be killed with the Dagger and the powers would pass on to the killer. It's easy to imagine her carrying with her not to risk anyone finding and taking it, being ambuished, and then whomever tried to off her used it because it was the first weapon readily available there. There we have the second Dark One, and so on.
