The badik or badek (Makassarese: ᨅᨉᨗ badiʼ, Buginese: ᨀᨓᨒᨗ kawali) is a knife or dagger developed by the Bugis and Makassar people of southern Sulawesi, Indonesia.

Some versions from Sulawesi are decorated with inlaid gold figure on the blade called jeko.

[4] As with other blades in the Malay Archipelago, traditionally-made badik are believed to be imbued with a supernatural force during the time of their forging.

When both men are inside, an agreement to fight til death and thereafter shall be no hereditary grudge nor will any party be allowed to question the duel, shall be made.

[6] Because avoiding injury is near-impossible even for the victor, this type of duel was considered a sign of extraordinary bravery, masculinity and the warrior mentality.

Although true sitobo lalang lipa are no longer practiced, enactments of these duels are still performed at cultural shows today.

Lethal penetration in selected vital anatomical targets can be surely made with less than 3 in (76 mm) of the blade [5]: 157
