Developed in the early 20th century, the 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 WWI 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 1915 bolos remain. 21 inches overall, with a 15 3/4 inch blade dated "1916" on the left ricasso and marked "US/1324" on the right. Wood grips, with an "eagle beak" pommel and standard 1905-style locking hardware. Similar examples are illustrated in the book U.S. Military Knives, Bayonets and Machetes, Vol IV by Cole.

Fine, with mild spotting on the blade and light sharpening marks. The grips show some light dings and scuffs, with a mixed brown and gray patina on the guard and half of the faded original blue remaining on the pommel.
