Description: |
These machine refinements moderate the cutting force according to the width of the file at that point, and also space the cuts farther apart on the wider part of the file.The inventor was superintendent of the Arcade File Works and this machine was likely used by them. They did not manufacture machinery for the use of other file makers. |
