A type of ratchet in which a cogwheel and stiff wooden tongue are held in a frame and mounted on a handle, which rotates freely. The player holds the handle and swings the whole mechanism around, which makes the tongue click against the cogwheel and produce a very loud clicking sound.
This style is.similar to a football rattle, which is sometimes used in its place when a particularly loud sound is needed. A popular design consists of a thick wooden cogwheel with two wooden flanges that alternately hit the teeth of the cog when the device is spun.
