And apparently the creator of the "Ever-Ready Sharp Pencil" in Japan went on to found the electonics company "Sharp", whose name is derived from the pencil: > The mechanical pencil became successful in Japan with some improvements in 1915 by Tokuji Hayakawa, a metalworker who had just finished his apprenticeship. It was introduced as the "Ever-Ready Sharp Pencil". Success was not immediate since the metal shaft—essential for the pencil's long life—was unfamiliar to users. The Ever-Ready Sharp began selling in huge numbers after a company from Tokyo and Osaka made large orders. Later, Tokuji Hayakawa's company got its name from that pencil: Sharp. https://en.wikipedia.org/wiki/Mechanical_pencil https://en.wikipedia.org/wiki/Mechanical_pencil
