Historical information

The subject item is a saw blade sharpening clamp that attaches to a bench allowing the operator to sharpen the teeth on a saw with a file while keeping the saw blade in an upright position.

Henry Disston (1819–1878) began his career as an American saw maker in Philadelphia. He emigrated from England in 1833 and started making saws and squares in 1840. In 1850, he founded the company that would become the largest saw maker in the world the ”Keystone Saw Works” on the Delaware River.
Some five years later, Disston built a furnace possibly the first melting plant for steel in America and began producing the first crucible saw steel ever made in the United States. While his competitors were buying good steel from Britain, he was making his own, to his specification, for his own needs. Disston subsequently constructed a special rolling mill exclusively for saw blades.
Over the following decade, the Disston company continued to grow, even while dedicating itself to the Union Army's war effort. In 1865, when his son Hamilton Disston rejoined the business after serving in the Civil War, Disston changed the company's name to Henry Disston & Son. Henry Disston and his sons set the standards for American saw makers, both in terms of producing high-quality saws and developing innovative manufacturing techniques. Disston also started making files in 1865.
In September 1872, Henry Disston and two other men dug a part of the foundation for what was to become the largest saw manufacturing facility in the world: Disston Saw Works. This was in the Tacony section of Philadelphia. Having previously moved his expanding business from near Second and Market Streets to Front and Laurel Streets, Disston sought to establish his business away from this cramped area. It took over 25 years to move the entire facility to Tacony. This Philadelphia neighborhood seems to have been the only company town in the United States established within an existing city. At its peak of operations, Disston Saw Works employed 8,000 people and the factory covered 300 acres.
The company, known as Henry Disston and Sons, Inc by the early 20th century, cast the first crucible steel in the nation from an electric furnace in 1906. The firm's Armour plate building near Princeton Avenue and Milnor Street contributed tremendously to the World War II effort. But the company's innovation and industriousness would not last forever. In 1955, with mounting cash-flow problems and waning interest on the family's part to run the firm, Henry Disston and Sons were sold to the H.K. Porter Company of Pittsburgh.
Porter's Disston Division was sold in 1978 and became the Henry Disston Division of Sandvik Saw of Sweden. This division was then sold in 1984 to R.A.F. Industries of Philadelphia and became known as Disston Precision Incorporated, a maker of specialized flat steel products. In 2013, R.A.F. Industries sold Disston Precision Inc. in a private sale. Although the company has ceased making Disston handsaws, the Disston brand name still exists in this firm.
