Before the advent of iron working on Taiwan, the indigenous people generally used bamboo knives. Iron knives became popular later. Their knives were usually made in the shape of a leaf, less than 34cm in length, with a wooden scabbard, and were worn arounhe waist using a rattan belt. The parts with lighter color and the two ears are the places where rattan strips were wrapped. Besides being used as a weapon, knives like this were used to cut meat, skin animals, and were essential in carving bamboo and wood. The scabbard is decorated with geometric patterns.
