The shaft is sunk into the end of a rod of hard wood and secured with gutta and fine rattan lashing.

The blade of the knife is held between the thumb and finger of the right hand, the cutting edge directed forwards, and the long handle is gripped between the forearm and the lower ribs; the weight of the body can thus be brought to the assistance of the arm in cutting hard material. With this knife most of the finer carving is done, the adze and sword being used chiefly for rough shaping.
The adze consists of a flat blade of steel in the shape of a highly acute-angled triangle (PI. 111). _ The slightly convex base is the
