A quiet little Shaker woman named Tabitha Babbitt watched the men working in the saw mill. She noticed that the long two-man pit saw the loggers used was wasting motion, as the saw only cut one way. Using her knowledge of the weaving machine, she created a circular saw blade & mounted it on a spinning axel at a high rate of speed. She is also credited with invention of machine-cut nails. She valued a simple life & never patented any of her inventions.

Cyrus McCormick son of Robert McCormick the initial inventor of the mechanical reaper.
