Disston Saw Works
Disston Saw Works of Philadelphia was one of the better known and highly regarded manufacturers of handsaws in the United States. During the Machine Age, as Henry Disston & Sons, Inc., it was a supplier of industrial saw blades. A successor corporation, still active in Philadelphia, is called Disston Precision.
==History==
The story of handsaws in the United States mirrors the technical and political development of steel. Sheffield, England, was the center of handsaw production during the 18th century and through most of the 19th century because of its fine steel and skilled craftsmen. But England's political and economic lock on steel making in the colonies held American sawmakers at bay until well after the Revolutionary War. American steel producers could not compete until import tariffs leveled the playing field in 1861.
