Boston was founded in 1899; in 1999 they celebrated with a 100th anniversary sharpener. In 1913, their sharpener, the Boston Pencil Pointer, was selling for about $6. In the past, people were used to more expensive sharpeners or having to sharpen pencils by knife, which wasted the lead.
Also, how did John Lee Love invented the pencil sharpener?
He applied for a patent for a portable pencil sharpener in 1897. His application specified that his invention was an “improved device” that could double as a paperweight or ornament. The design was simple, including a hand crank and a compartment to capture the pencil shavings.
