Abstract
This paper reveals the development process of reversing saw based on literary materials and real saws themselves. As a result, the following facts have been found.
(1) It was found in one of the documents that the kind of reversing saw that is shaped like fine work saw with its head split in two, existed in the region of Tokyo prefecture in 1877 (the tenth year of Meiji) .
(2) The inspection of the kind of reversing saw that appeared in the early Meiji era revealed that it is characterized by the shorter neck and tang compared to what we currently have, and Tamahagane (jewel steel) is used as a material to make the blade.
(3) Behind the spread of reversing saw was the generalization of western steel (Togo Steel) as a material for blades and oil hardening technique, and the pursuit of convenience.
