Also known as: 額当て, 鉢金, 护额
A piece of protective gear for the forehead. May be in the form of a metal plate attached to a cloth Headband (as in Naruto (Series), where most Ninja wear such headgear with their village's symbol engraved on it), an entirely metal headband, or even a metal piece on the forehead which seemingly isn't held in place by anything at all (i.e. Leona (League) in League Of Legends).
