Kodayani is a handmade nail used for fixing the brass motifs on Nettur petti which has aesthetical as well as functional qualities. ‘Kuda’ in Malayalam means umbrella and ‘ani’ means nails, so the name suggests the shape of nail. The umbrella part of the nail is done by pressing a brass piece. A small piece of brass is placed inside the die and hammered once; it obtains a form of semi-hemispherical from and flat from other side. Afterward with the use of a pointed chisel a dimple is made on the flat side. Once it is done a thin nail is hammered on the flat surface of the brass piece using punch tool. Once the nail is made it is buffed and polished.
