"An example of Tausug woodwork is the puhan (wooden handle) of bladed weapons which may be simple or decorated with gold or silver wires, strings, and rings. For the barong, the handle is wrapped in cord and metal at the far end, and carved and polished at the upper part. At the end of the grip is a protrusion carved with ukkil designs. The handle of the kalis, which the Tausug terms as daganan kalis, can also be profusely decorated, sometimes with mother-of-pearl. Taguban (scabbards) are beautifully carved and are covered with
budbud (fine rattan). Other woodworks include kitchen utensils and furniture items like beds, chests, and wardrobes (Szanton 1973:51–54)."
