With a '''shaker''' [[mechanical pencil]] it is possible to advance the lead with a rapid shake of the pencil, in addition to the classic push button mechanism; this solution makes it easier to quickly extend the lead without changing the finger grip.
Inside the body of the pencil there is a sliding weight (usually in the form of a metal coil) that activates the mechanism to advance the lead at every shake.
In some models there is also a feature which prevents the shaker mechanism to dispense the lead when the pencil is in a lock position.
