Triangular-headed iron projectile point with a barb at the head's base (left) and a long tang (right). To make an arrow (snini in Nafaanra), the tang was inserted into a straight shaft made of bamboo, reed or lightweight wood to which it was hafted. This artifact was found in an area (mound 7) that archaeologists interpret as a house mound. The projectile point shows signs of corrosion by rusting. Scale in cm. Length: 9 cm. Weight: 9.2 g.
