The activities of [[Eversharp]] in the field of writing instruments began in 1914 with the launch of homonym mechanical pencil. For many times it was said that that was 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 [http://en.wikipedia.org/wiki/Sharp_Corporation Sharp]. In reality [http://www.vintagepens.com/Eversharp_history.htm subsequent searches] have shown that the pencil ''Eversharp'' was invented by Charles Keeran in 1913, and then the invention was sold for production to the ''Wahl Adding Machine''.

In 1917, continuing with its policy of expansion, the [[Eversharp|Wahl Eversharp]] acquired the ''[[Boston Pen Company]]'', a company that already started producing good fountain pen in ebonite characterized by a clip wheel. The pens were marketed branded [[Eversharp|Wahl]], promoting as capable to alleviate the wear on the edges of the pockets thanks to their peculiar ''Roller Clip''.

In 1917, continuing with its policy of expansion, the [[Eversharp|Wahl Eversharp]] acquired the ''[[Boston Pen Company]]'', a company that already started producing good fountain pen in hard rubber characterized by a clip wheel. The pens were marketed branded [[Eversharp|Wahl]], promoting as capable to alleviate the wear on the edges of the pockets thanks to their peculiar ''Roller Clip''.

The success of the new model, called [[Tempoint]] was great and [[Eversharp|Wahl Eversharp]] climbed on top of sales ranking, but the unexpected success involved considerable problems for the production, which was not efficient. That is why the company invested heavily in improving production structures and in 1921 launched a new line of metal pens, called [[Wahl Engine Turned|Wahl All Metal Fountain Pen]] for which they have prepared an efficient production line. These pens have not to be confused with an earlier production line, dated between 1919 and 1920, of overlayed metal pens,<ref>As reported in http://www.fountainpennetwork.com/forum/index.php?s=aca8536317f4b3a8bae7a3774b333542&showtopic=199</ref> still using the ''Roller Clip''.
