The inventor of the electric pencil sharpener created it to improve efficiency and convenience in sharpening pencils, eliminating the need for manual sharpening. They wanted to provide a quicker and more precise way of sharpening pencils in various settings like classrooms and offices.
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.
Unplug the electric pencil sharpener to avoid safety hazards. Use tweezers or pliers to carefully extract the eraser from the sharpener's blade or opening. Be cautious not to damage the blades or any internal components of the sharpener during the process.
A typical electric pencil sharpener uses around 20-30 watts of power. This amount may vary depending on the size and type of the pencil sharpener.
After a pencil is sharpened, the extra materials left in the sharpener are known as pencil shavings. These should be dumped regularly as old-school electric pencil sharpeners have been known to rarely catch on fire due to an overflow of pencil shavings in the machine.

John Love did not invent the pencil sharpener. The first patent for a pencil sharpener was actually granted to Walter K. Foster in 1855. Love did, however, patent improvements to the pencil sharpener in 1897, which allowed for a more efficient and effective sharpening process. Love's contributions helped to advance the design and functionality of the pencil sharpener.
