Some shaker pencils. Left to right: a Pilot Delful The Shaker, a Pilot Dr. Grip Equilibrium, two Pentel Jolt (0.5mm and 0.7mm), a BIC AI, and an economy unbranded model

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. 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.
