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.
