The Beater's bat is a piece of equipment used by Beaters, in the game of Quidditch, to hit Bludgers keeping them away from their own team members and hitting them at the players on the other team. The bats were magically reinforced to give them greater strength. In the early days of the game, when Bludgers were made of rock, the bats would often shatter the rock, resulting in flying gravel. After that they used lead Bludgers, but the bats proved to be too strong for them also, denting them when they were struck. The Bludgers made of iron were strong enough to not break when hit by the bats.
