This maker of saw sharpening machinery was established sometime shortly after 1904 by Edward P. Armstrong. Their early product line consisted of saw sharpening tools, and soon expanded to include more automated sharpening machines and stretcher rolls. They remain in the same business today, although their current product line is thoroughly modernized, with CNC throughout.
