Wizards' Staffs

Of all the wizards in Tolkien's works Gandalf and Saruman the White are the most iconic. Their struggle against one another is so powerful that it is often viewed as the ultimate clash between good and evil besides Gandalf's frequent other attempts to fight Sauron threw out the lord of the rings. Yet there weapons are not the stuff of mortal men or elves and dwarfs like swords, axes and bows but simple wooden staffs. These staffs can transmit wizard's magic in to the material world and are a symbol of thare otherworldly identity as messengers of the Valar. But fore the most part we don't know how these staffs are constructed or thare historical value like the sword of aragorn anduril. In the films Gandalf returns from the dead as gandalf the white with a knew staff but who gave it to him. Could it be from Valenor or perhaps from Galadriel. Who knows where Saruman gained his staff from. Surely one of the Valar could have produced it but there is no evidence to suggest this. I doubt that these staffs could have been made by the wizard's themselves because when Gandalf snaps Saruman's staff before the foot of Orthanc Saruman seems distressed. When Gandalf destroys the staff he says that his enemy has been cast from the order of wizard's so does that suggest that the majority of a wizard's power comes from his staff. It can't be possible when I know think about it to rebuild a staff or make one from a Wizard's perspective since Saruman does not have a staff when he meets Frodo at the end of the return of the king. Anyway it remains a mystery.
