Stated purpose: "In the 19th century a standard set of 36 brace bits
included a forked turnscrew bit - which was used for tightening split
saw nuts. It was an important bit to the carpenter because with changes
in weather it was (and is) not unusual for a handle to loosen. So having
a standard bit to tighten it up made for good sense and much more
satisfying sawing. "
