"A Bolo is a short, broad, lance-shaped weapon; used by the Filiinos in their operations against the American troops. The blade is about 18 inches in length by nearly 3 inches in breadth at its broadest dimension. It tapers from the middle toward the haft as well as toward the point, making it strongly resemble the ancient short sword. It is not double edged, however, but tapers from a thick back to an extremely keen edge. In April 1904, the United States troops operating in the Philippines, were supplied with bolos."—(Charles Leonard-Stuart, 1911)
