Mechanical Energy

Explanation:

According of law of conservation of energy, energy can neither be created nor be destroyed. It can only transformed from one form to another.

When electric sharpener works by using electrical energy, it is being used to drive the blades of the sharpener and is being converted to mechanical energy which is then converted to heat energy and the sharpener gets warm.

Electrical energy is the energy possessed by virtue of motion of electrons.

Mechanical energy is the energy possessed by a body by virtue of its position and motion.

Heat energy is the transfer of thermal energy from hotter body to colder body.
