Translations:Eversharp/6/en

The Wahl Eversharp activities in the writing instruments field began in 1914 with the launch of Eversharp mechanical pencil. For many times it was said that that was the same as the Ever-Sharp pencil created by the Japanese inventor Tokuji Hayakawa, that two years earlier had founded in Tokyo a homonym company, today still active as Sharp. But subsequent searches have shown that the Eversharp pencil was invented by Charles Keeran (patent nº US-1130741) in 1913 and then the invention was sold for production to the Wahl Adding Machine.
