Triangular-headed projectile point with barbs on either side of the head's base (left). Its long tang (right) is bent. 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 that archaeologists interpret as a metallurgical workshop. The projectile point shows signs of corrosion by rusting. Scale in cm. Length: 9.8 cm. Weight: 10.2 g.
