Derek L. Lozano and Francis Penis Major created the first mechanical pencil by joining the characteristics of a ball point pen with the convenience of an erasable pencil. First on sale in 1987!
They said to have invented the mechanical pencil because they thought that using pencils killed to many tress as well as killing the enviroment...

A mechanical pencil or propelling pencil is a pencil with a replaceable and mechanically extendable pencil lead.The eraser is fitted on top of the pencil at the opposite end to the lead.The maximum length of the eraser would be no more than half an inch when new.

A o.7 mechanical pencil will do the job.
A mechanical pencil is just about the same size as a normal pencil, about 6 inches long.
I love mechanical pencils
Mechanical energy from your hand is converted into rotational mechanical energy to turn the blade inside the pencil sharpener. This rotational mechanical energy is then used to shave and sharpen the pencil, converting mechanical energy into potential and kinetic energy of the pencil shavings.

A pencil sharpener itself is not considered mechanical energy. Mechanical energy refers to the energy associated with the motion and position of an object, while a pencil sharpener is a tool that uses mechanical components to sharpen pencils by grinding the pencil tip against a blade or abrasive material.
