A scold’s bridle is a type of gag used historically as a form of punishment for those labeled slaves, witches, or nagging women known as scolds. Modern versions of the scold’s bridle are sometimes incorporated into BDSM play.
A scold’s bridle is made up of a metal muzzle embedded in a cage-like frame enclosing the head. The muzzle section has a bridle bit that enters the wearer’s mouth and pins down their tongue. Historically this bit may be spiked to ensure the wearer’s silence. The scold’s bridle locks at the neck.
A scold’s bridle is often called a brank’s bridle, or branks for short.
