Why did John Love invent the pencil sharpener?

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.
