To'i. Hafted adze. Dark basalt ofa'i (stone) is worked and polished into a Fao'a (adze), triangular in section. The Fao'a has flaked sides with a large bevel and cutting edge. Its blade is flat and smooth. The Fao'a is lashed securely to the carved 'Ā'au (wooden haft) with braided nape (coconut sennit). A small piece of skin (possibly shark skin) is wedged in between the stone and the nape for extra grip. The 'Ā'au has a pronounced triangular heel and a long cylindrical to'o (shaft) for grip. A hole is drilled through the butt for suspension. The 'Ā'au and nape components are brown in colour, and the Fao'a is dark in colour.
