Probably the most dramatic and certainly the most varied metal currency forms are objects believed to be derived from implements and weapons. Popularly known respectively as hoe money and throwing knives, these objects were fabricated from copper, bronze, brass and iron.

Hoe money came in the shape of a heart, spade, paddle, teardrop, trowel, anchor or blade. In fact, the shapes began to overlap with the objects classified as knives or blades. Hoe money varied in value but was most often used as bridewealth. It was also frequently re-formed into other objects or implements as needed.

Currency derived from the throwing knife also came in many shapes and sizes, but its distinctive feature is the complexity in the orientation and size of its blades. These flattened shapes, often very thin, posed technical challenges to the blacksmith that required considerable skill and craftsmanship. In addition, many of the throwing knives were elaborately decorated, some on the blades and others only on the handles. Throwing knives are reported to have been used for bridewealth. Other evidence suggests, however, that they were emblems of office or status, carried in dances or other ceremonial occasions, and not currency at all.
