Curved and spurred, waka kiakavo club. These are heavy, two handed clubs developed to be a very effective offensive and defensive weapon. The spur is designed to parry attacking blows, while the heavy wedge shaped head is designed to maximise the force placed on a small area. In many cases saplings were grown into the right shape, increasing the strength of the club and decreasing the necessary woodwork. The waka kiakavo is a heavy fighting club with a distinctively ridged and furrowed inner curve under the head achieved by distorting the living sapling. It also has an ornamental ridge inside the fork of the head.
