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 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.
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.
When using an electrical pencil sharpener, electrical energy from the power source is transformed into mechanical energy to rotate the blades of the sharpener. This mechanical energy is then used to sharpen the pencil by cutting away the wood and graphite.
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.

electric energy to kinetic energy to heat energy
If it were, it would be rather difficult to lift, and probably too big to fit a pencil through. A pencil sharpener is more likely to weigh 50 grams, if it is one of a mechanical variety.
An electric pencil sharpener typically operates on standard household electricity, which is around 120 volts in the United States. The energy it provides is used to power the motor that rotates the sharpener blades to grind down the pencil tip.
Pretty much anything that uses electricity to run and has moving parts is this conversion. An example of this is a car, or a blender.
Bernard Lassimone, a French mathematician, invented the standard manual pencil sharpener in 1828. In 1847, Therry des Estwaux invented an improved mechanical sharpener.

Most mechanical parts for your Panasonic pencil sharpener will not be replaced by Panasonic and seem to be unavailable anywhere else, though they do have an exchange program to exchange the entire unit.
