Developed in the early 20th century, the Model 1915 Bolo bayonet was one of the U.S. Army's attempts at a hybrid weapon that could reduce the loadout an individual soldier had to carry into the field. Intended for use in jungle environments, the bolo could serve as both a bayonet and a brush clearing tool. Though the daylight bayonet charge was becoming a thing of the past, observers of World War I and the Russo-Japanese War noted the rise of the night attack and its resultant brutal hand-to-hand combat; the determination was made that a bayonet should be a fighting weapon and nothing more, and all the odd ducks and promising experiments were pulled from the field. Either destroyed or discarded as surplus, it is believed that only about fifty Model 1915 Bolo bayonets remain. 20 3/4 inches overall, with a 15 5/8 inch blade marked "SA/(flaming bomb)/1916" on the left ricasso and "US/5923" on the right. Walnut grip panels, with an "eagle beak" pommel and standard 1905 type locking hardware. Scabbard is absent.
