The men of Taiwan’s Austronesian tribes used knives that were both practical and decorative. The simple unelaborate knives were used as weapons, used in hunting and to clear foliage when walking. Exquisite knives with carvings or inlays were worn on special occasions with ceremonial clothes. In general, the knives of northern tribes were curved, while in the south they were straight bladed.
　　Binan tribe knives were tadaw which were weapons and kamut which were for everyday use. The latter had a small dagger as an accessory and an awl pasus, which was used to stitch up wounds. Knives used as weapons and their accessories were together called aliyut. When weapon knives were lost everyday use knives would be used as weapons.
