As the Henry Disston & Sons firm entered the 1950s financial problems arose the had to do with the transition to electric power tools, and other market forces. The Disston Company faced these problems using innovative materials and designs in their hand tools. The final new saw that was introduced before the acquisition of the company by Porter-Cable and the move of manufacturing to Danville, Virginia was the No. D-111, a lightweight designed saw with new nylon handle, similar, but simpler, to the design of the D-95 “Masterpiece” saw. The D-111 was apparently introduced in 1955 and produced for only that one year. This example of it (the only one I can remember seeing) is quite nice with a shiny blade and full etching only marred by a smudge or two of tarnish. The nylon handle with nickled-brass saw screws, including a “Disston / USA” medallion are without fault. So 1955, and this saw, marked the end of more than 100 years of Disston saw production in Philadelphia. The filing is 8ppi crosscut. It is sharp.
