The Clue of the Broken Blade is Volume 21 in the original The Hardy Boys Mystery Stories published by Grosset & Dunlap.

This book was written for the Stratemeyer Syndicate by John Button in 1942. Between 1959 and 1973 the first 38 volumes of this series were systematically revised as part of a project directed by Harriet Adams, Edward Stratemeyer's daughter. The original version of this book was rewritten in 1970 by Richard Deming resulting in two different stories with the same title.

Because of Dr. John Button's death in 1967, The Clue Of The Broken Blade (1942) entered the Canadian Public Domain on January 1, 2017.
