"Vintage Machinery" entry for Henry Disston & Sons
Description:
Set screws to secure/remove the handle as well as allow the handle's angle to be adjusted to suit the user's preference. This saw handle was offered in the 1876 Price List with a saw blade of comparable quality to the No 7.

Thomas Disston references his 3 JAN 1871 patent,110751, for a cross cut saw handle that uses the same premise and applies the principle to handsaws in this patent.
