A pencil has potential energy due to its position above the ground. This potential energy can be converted into kinetic energy when the pencil is dropped and accelerates towards the ground.
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 uses mechanical energy, as it harnesses energy through physical motion to sharpen a pencil.
The pencil resting on a desk has potential energy due to its position in the Earth's gravitational field. This potential energy can be converted to kinetic energy if the pencil is dropped or moved.
Mechanical energy from your hand turning the pencil sharpener's handle is transformed into kinetic energy as the blade inside the sharpener rotates and sharpens the pencil. Friction between the blade and the pencil also generates heat energy in the process.

The energy involved is primarily gravitational potential energy. As the pencil falls, this potential energy is converted into kinetic energy.
The potential energy of the pencil is being converted to kinetic energy as it falls due to gravity.
This actually got me for a while too. Take the eraser out of the top of the pencil and drop refill pencil graphite down the tube.
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.
Mechanical energy is converted into sound and heat energy when using a pencil sharpener. The mechanical energy from turning the handle is used to rotate the blade, which grinds the pencil lead to create a sharp tip. The sound comes from the friction between the blade and the pencil, while heat is generated from the friction between the blade and the pencil shavings.
It depends on the height from which you drop the pencil and the surface it falls on. A pencil may or may not break when dropped, as it could land in a way that prevents it from breaking or it could land with enough force to cause it to break.
