Two ivory harpoon heads tipped with iron blades. The body of each of the harpoon heads has a single set of paired barbs, and the iron blades are also barbed. The blades are secured in blades slot by rivets. One has a copper rivet, and the rivet on the other harpoon is made of iron. These items were originally identified in the Smithsonian Institution's catalogue as 'fish spear heads', but the size and style is consistent with harpoon heads used for hunting sea mammals.
