Traditional weapons - BADIK

The Badik is a traditional dagger which originates from the coastal tribes of southern Sulawesi such as the Bugis and the Makasarese. Because of their trade relationship with other tribes, it has reached the coasts of Sumatra, the Malay Peninsula and to some extent Borneo, Java and Bali.
The blade can be in iron, steel or pamor. It is also believed the Badik has mysterious power such as for the Keris.
The Bugis Badik has a 90° pistol grip with round edges, whereas the Makasarese badik has a 45° conic pistol grip. The Sumatra and Peninsula Badik is very similar to the Bugis.
The Badik is also part of the traditional clothing and is wear by the bride for the wedding ceremony in Sulawesi or Sumatra. It is worn in front of the stomach into the pleats of the sarong.
One of the traditional way of fighting with the Badik is to have the two opponents enclosed in sarong with a Badik in a hand while the other hand holds the sarong with no possibility to escape.

Traditional weapons - MANDAU

Mandau is the traditional weapon for the Dayak people of Borneo. However, Mandau is mostly ceremonial, and a less elaborate version is used as an everyday practical tool.
Associated with the Headhunting Ceremony, where people would gather to attack other tribes, and gather heads to be used in various festivities, mandau is both a work of art in itself and a formidable weapon.
The blade is mostly made of tempered metals, with exquisite vineworks and inlaid brass. The hilt is made from animal horns, such as deer's horns, although some variations with human bones and fragrant wood also have been found. Both the hilt and scabbard are elaborately carved and plumed. Details of carvings vary from tribe to tribe, but mostly depict creatures or, if human bones were used, anthropomorphic deities.
