Glamdring, Foe-hammer

[thekingofgondor]

I've always been under the impression that neither Gandalf nor Saruman had any intention of combating the other, knowing full well that releasing the other from their mortal shell could prove disastrous, as they would likely be able to confer with the Valar what had occurred (if Gandalf had, say, slain Saruman with Glamdring, as Saruman's treachery was not yet widely known, it would have looked like Gandalf had gone rogue and Saruman would have been sent back with the orders to break Gandalf's staff and cast him from the order, much like Gandalf ultimately did after his return) and return with the authority to strip the other of their power in Middle-earth. So Tolkien probably didn't bother mentioning what weapons Gandalf may or may not have carried as it was a moot point.
