The Disston No. 43 Combination Saw is one of the most admired saws that came from the factory of Henry Disston & Sons. It was the most advanced and most expensive in a line of "combination" saws that featured a square and ruler in their design. The saw was produced continually from 1858 to 1918.
The saw was based on three patents:
1.Patent 14,863 - 05/13/1856: Improvement in the Construction of Handsaws by Jackson Gorham
2.Patent 20,313 - 05/18/1858: Device Attached to Handsaws for Squaring and Marking by Hiram Smith, assignor to Henry Disston.
3.Patent 20,337 - 05/25/1858: Leveling Device Attached to Hand-Saws by Henry Disston and Thomas L. Morse.
