Who Created the First Pencil Sharpener?

TL;DR

The first mechanical pencil sharpener, known as the 'taille crayon,' was invented by Bernard Lassimone in 1828. Although it improved efficiency over manual sharpening, it was still not significantly faster. Subsequent innovations, including the conical design by Therry des Estwaux and electric versions, ultimately revolutionized the sharpening process.

Transcript

For years, the knife was the most commonly used tool to sharpen the wooden writing instrument known as a pencil (which historians believe was invented in the 15th or 16th century). But whittling the wood away to eventually produce a point was a time-consuming, tedious, and inexact process. As pencils became more ubiquitous in everyday life, it beca... Read More

Questions & Answers

Q: Who invented the first mechanical pencil sharpener?

The first mechanical pencil sharpener was invented by Bernard Lassimone in 1828.

Q: What was the problem with early pencil sharpeners?

Early pencil sharpeners required the user to either twist the pencil or the sharpener to achieve a sharp point.

Q: How did Therry des Estwaux's invention improve the sharpening process?

Des Estwaux invented a conical-shaped device that allowed all sides of the pencil to be whittled away at once, making the sharpening process much quicker.

Q: When were electric pencil sharpeners commercially produced?

Electric pencil sharpeners were first commercially produced in 1917 by Farnham Printing & Stationery Co, but they didn't become widely available to the public until the 1940s.

Summary & Key Takeaways

• The first mechanical pencil sharpener, known as the "taille crayon," was invented in 1828 by Bernard Lassimone and was only slightly more efficient than using a knife.

• In 1837, the British introduced the "Styloxynon," which was similar to Lassimone's sharpener but still required rough pointing with a knife.

• A conical-shaped device, invented by Therry des Estwaux in the 1840s, allowed for quicker sharpening of pencils and became known as a prism sharpener.

• Walter K. Foster patented the first American pencil sharpener in 1855, which improved on the conical design and enabled mass production.
