The M-1909 Bolo Knife was designed to aid US soldiers with jungle foliage that they found themselves in with incursions into Cuba and the Philippines, where natives used similar sized machetes. It was designed to be carried as a belt knife from its first production at the Springfield Armory in 1909 to its final production in 1915. Only 17,540 were produced at the Springfield Armory making originals pretty rare. Beginning in 1917 a variant of the M-1909, designated as M-1917 Bolo Knife was introduced. Tempered, high carbon steel blade with proper markings of the era. Steel finger guard and wood grip. Heavy leather scabbard has slotting pin in the metal throat and accurately replicates Rock Island Arsenals issue from the era.
