Michelangelo's David Holding Secret Weapon?

Nearly everyone in the world has either heard of the Statue of David or the great Michelangelo, but what people never realized until now was the entire time David has been holding the remnants of a weapon in his right hand. For centuries people have looked at the Statue of David without realizing his right hand ws holding what was left of a staff used for combat. This weapon was used as a staff with a sling attatched to the end in order to throw rocks or other small objects great distances. In the bible it is said that David defeated Goliath with a similar weapon to what Michelangelo gave his statue. The reason why the rest of the staff was never added was because the statue was mounted in front of the Piazza della Signoria. While some people disagree on whether or not the weapon was actually a staff or not, the fact remains that the Statue of David is holding some unknown object in his right hand and it will continue to hold it for as long as the statue stands.
