Pencil sharpener. A pencil sharpener (also referred to in Ireland as a parer or topper) is a device for sharpening a pencil's writing point by shaving away its worn surface. Pencil sharpeners may be operated manually or by an electric motor.
According to the folks at Pencil.com (who ought to know) pencils have been around in various forms since the 16th century. Long acknowledged as an improvement over earlier writing implements, sharpening them had always been kind of a hassle; whittling with a knife requires a skilled hand. But then in 1828 a Frenchman named Bernard Lassimone invented the first mechanical pencil sharpener. As noted by The Early Office Museum, this sharpener employed small metal files set at 90 degrees in a block of wood and worked to scrape and grind the edges of the pencilâs tip.
