Archaeologists conclude that the presence of both stone and iron tools can represent different stages of technological development within Bantu-speaking societies. It is possible that earlier Bantu groups used stone tools before adopting ironworking techniques, or that certain Bantu communities continued to use stone tools alongside iron tools for specific purposes. However, the presence of iron tools is generally seen as indicative of the Bantu's advanced metalworking skills and their cultural influence in shaping the Iron Age in Africa.
