Luba people
With settled communities, states Thomas Reefe – a professor of History, the Luba people had developed metal extraction techniques, skills to make utilitarians products from them and "high degree of craft specialization". The metal working techniques in use by the early Luba people included drawing out thin wires, twisting and laminating them, plaiting them into complex well designed shapes such as necklaces, bracelets and hooks for fishing, needles for sewing and such.
