Wahl Eversharp Pens

In 1913, Charles Keeran invented a mechanical pencil with lead so thin it didn't have to be sharpened, but thick enough that it wouldn't break too easily. He did a manufacturing and production deal with the Wahl Adding Machine company, and the Eversharp was born. Wahl forced Keeran out in 1917, and after making pencils for a few years, added a line of self-filling fountain pens in 1921. Early Wahl pens are quite collectible, as are the pencils. The company produced both pens and pencils until the late 1950s.
