Historical origin of pencil sharpener

Pencil sharpeners must be familiar to everyone. This is a pencil sharpener. In the17th century, people just sharpened pencils with knives. With the progress of society, by the beginning of19th century, people not only need to use more pencils, but also have higher requirements for the time spent sharpening pencils. The automatic pencil sharpener was born in this environment. The first such pencil sharpener in the world was invented by a Frenchman in 1828. In the next few centuries, the pencil sharpener gradually developed into a familiar appearance for adults.

The golden age of pencil sharpener was probably from the mid-1980s to the early 1990s, when automatic or electric pencil sharpeners appeared. The traditional pencil sharpener slowly withdrew from the historical stage.
