Weapons changes

Shaka is often said to have been dissatisfied with the long throwing assegai, and is credited with having introduced a new variant of the weapon: the iklwa, a short stabbing spear with a long, broad, sword-like spearhead.

Although he is credited with introducing the ilkwa to his people, Shaka likely did not invent it himself. He most likely outsourced it from Nzama, who later had a feud with him because he did not want to pay for the spears. According to Zulu scholar John Laband, Shaka insisted that his warriors train with the weapon, which gave them a "terrifying advantage over opponents who clung to the traditional practice of throwing their spears and avoiding hand-to-hand conflict." The throwing spear was not discarded, but used as an initial missile weapon before close contact with the enemy, when the shorter stabbing spear was used in hand-to-hand combat.

It is also supposed that Shaka introduced a larger, heavier version of the Nguni shield. Furthermore, it is believed that he taught his warriors how to use the shield's left side to hook the enemy's shield to the right, exposing the enemy's ribs for a fatal spear stab. In Shaka's time, these cowhide shields were supplied by the king, and they remained the king's property. Different coloured shields distinguished different amabutho within Shaka's army. Some had black shields, others used white shields with black spots, and some had white shields with brown spots, while others used pure brown or white shields.
