Vatuvi

Vatuvi is the name of a magical axe, used in the agricultural rites of the Trobriand Islands. The word "denotes 'setting up,' 'establishment,' 'firmness,' 'strong grip,' perhaps also a tendency groundwards" (Bronislaw Press, Coral Gardens and Their Magic - A Study of the Methods of Tilling the Soil and of Agricultural Rites in the Trobriand Islands, Vol. II: The Language of Magic and Gardening, 2007).
