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. 20 5/8 inches overall, with a 15 1/2 inch blade marked "SA/(bomb)/1916" on the left ricasso and "US/6005" on the right. Wood grips, with an "eagle beak" pommel and standard 1905-style locking hardware. A period modified brown leather sheath with belt hanger is included. Serial number 6005 was used as a reference piece in the book "U.S. Military Knives, Bayonets & Machetes, Volume IV" by M.H. Cole; aside from the smooth grips, this bayonet is a spot-on match for the illustrations. In this book, the bayonet receives a 4 page spread of illustration and detail, showing the differences between the Bolo model and the conventional bayonets made in the same year,

Good. The blade shows a mixed gray patina with shallow pitting and a few mild sharpening marks along the edges. Similar color and aging is visible on the hilt, with a darker tone to the pommel and a few light dings and scuffs on the grips. The modified sheath is fair with stains, dark spots, scuffs and cracks.
