Bolo Knife
The bolo is the broad-bladed working knife of the Philippines — wider toward the tip, weighted for the chop, the universal tool of field and jungle — and a weapon with a genuine military career: the blade of the Philippine Revolution and the guerrilla resistance of World War II, and, in an unusual compliment, an official issue pattern of the United States Army, whose M1904 and M1917 bolos equipped engineers, medics, and machine-gun crews through two wars.
