Overview

Eversharp is an American writing-instruments brand whose history began with Charles Rood Keeran's development of a commercially successful mechanical pencil. Keeran's work emerged from a period in which mechanical pencils were technically possible but had not yet achieved broad consumer acceptance. He believed that customers who paid premium prices for fountain pens might also pay for a well-made, dependable pencil. His early pencil patent was filed in 1913, and the first Eversharp pencils were test-marketed during the 1913 holiday season at Wanamaker's in New York City. Keeran initially operated through Keeran & Co., established in Bloomington, Illinois, and used outside manufacturers for production. The Heath Corporation of New Jersey made the first production pencils, while later manufacturing arrangements involved the Wahl Adding Machine Company of Chicago. In 1915, Keeran moved operations to Chicago and entered into an agreement with Wahl. Wahl took control of the Eversharp business in exchange for capital, and by the end of 1916 the company had absorbed the operation through a stock exchange. Keeran retained a minority interest and became sales manager for a time, but he had left the business by the end of 1917. The Eversharp pencil became a major commercial success. More than 12 million units had reportedly been sold by 1921, helping Wahl establish itself as a significant writing-instruments manufacturer. Wahl also entered the fountain-pen market in 1917 after acquiring the Boston Fountain Pen Company. During the early period, Wahl was used primarily for pens and Eversharp for pencils. By the end of the 1920s, the combined business adopted the Wahl-Eversharp name and used it across its product range. In 1941, the company shortened its corporate name to Eversharp. During the 1940s, Eversharp remained a major competitor in writing instruments and marketed mechanical pencils and fountain pens under a range of designs. Its efforts to enter the emerging ballpoint-pen market, however, were unsuccessful and contributed to the company's decline. Parker Pen acquired Eversharp in 1957. Parker continued using the Eversharp name for a limited period, but production of Eversharp-branded pens and pencils eventually ended. The name remained in use for refills and related accessories until 1999, including products intended for use with instruments from other manufacturers. The brand was later targeted for revival. From 2004, Syd Saperstein in the United States and Emmanuel Caltagirone in Italy worked on independent efforts to bring back the Wahl-Eversharp name before joining forces. In 2012, the new venture obtained abandonments of the original Wahl and Eversharp trademarks and filed new marks for the Wahl-Eversharp Company, a wholly owned subsidiary of Arizona-based Pensbury Manor LLC. The revived business produces modern fountain pens inspired by historical Wahl and Eversharp designs and patents. As a result, Eversharp has both a substantial historical identity as a mass-market American writing brand and a contemporary identity centered on heritage-oriented fountain pens.

History

Charles Rood Keeran, a native of Bloomington, Illinois, developed the idea for a more reliable mechanical pencil after earlier work in the pickle and jar-lid businesses. His first known pencil patent dates from October 1913, and he received U.S. Patent 1,130,741 in March 1915. The earliest Eversharp pencils were manufactured by the Heath Corporation in New Jersey and test-marketed at Wanamaker's in New York during the 1913 holiday season. Keeran later returned to Bloomington and organized Keeran & Co. to commercialize the product. The pencil used a narrow lead that helped establish a thin mechanical-pencil format in the market. In 1915, Keeran relocated operations to Chicago and contracted with the Wahl Adding Machine Company to manufacture Eversharp pencils. Wahl took control of the business after providing $20,000 in capital, and it completed the absorption of Eversharp through an exchange of stock in 1916. Keeran remained involved as a minority shareholder and sales manager for a limited period but was no longer with the company by the end of 1917. The product's rapid sales growth made Eversharp a major contributor to Wahl's expansion in writing instruments; more than 12 million pencils had reportedly been sold by 1921. Wahl expanded into fountain pens in 1917 through the acquisition of the Boston Fountain Pen Company. Initially, the company used Wahl for its pens and Eversharp for its pencils. By the end of the 1920s, it had adopted the combined Wahl-Eversharp identity, applying the name to its broader product range. The business became Eversharp in 1941 and remained a prominent participant in the writing-instruments market throughout the 1940s. The company's decline was linked in part to its difficulty competing in the new ballpoint-pen category. Its attempts to establish a successful ballpoint offering weakened the business, and Parker Pen acquired Eversharp in 1957. Parker retained the Eversharp name for several years, but eventually discontinued Eversharp pens and pencils. The name survived on refills and compatible accessories until 1999. A modern revival began in 2004, when Syd Saperstein in the United States and Emmanuel Caltagirone in Italy pursued separate efforts to restore Wahl-Eversharp. They later collaborated, and in 2012 their venture obtained abandonments of the original Wahl and Eversharp trademarks and filed new marks for the Wahl-Eversharp Company. The revived company operates as a wholly owned subsidiary of Pensbury Manor LLC and produces fountain pens influenced by original Wahl and Eversharp designs and patents.

    The original Eversharp product was a metal mechanical pencil designed by Charles Rood Keeran.
