The canoes were called Kájef and were made of bark, with tools of bone and stone.
The building technique was as follows: they flattened the bark under the water, laying great stones on top of it.
To achieve the required form, they softened them with fire.
The bark was sewn in spirals, with vegetal strips that allowed the assembly of the pieces.
A compact mixture, made with roots and mud, was used as caulking for the canoe.
They had several types of harpoons and lances, some with detachable tips that were let loose after striking the animal.
Hand stones, garrottes and small boleadoras, were their main weapons for marine hunting.
Among their tools, the three-pronged harpoon for fishing may be mentioned. In order to cut meat and firewood, they used large sharp mussel shells ».
