Sjambok
The sjambok (IPA: [ˈʃæm.bʌk, -bɒk]) or litupa is a heavy leather whip. It is traditionally made from an adult hippopotamus (or rhinoceros) hide, but is also commonly made out of plastic.
A strip of the animal's hide is cut and carved into a strip 0.9 to 1.5 metres (3 to 5 ft) long, tapering from about 25 mm (1 in) thick at the handle to about 10 mm (3⁄8 in) at the tip. This strip is then rolled until reaching a tapered-cylindrical form. The resulting whip is both flexible and durable. A plastic version was made for the South African Police Service, and effectively used for riot control.
The sjambok had a variety of uses, with the most obvious being cattle driving. It was heavily used by the Voortrekkers driving their oxen while migrating from the Cape of Good Hope. Even today, the sjambok is used by herdsmen to drive cattle. They are widely available in South Africa from informal traders to regular stores from a variety of materials, lengths and thicknesses. They are an effective weapon to kill snakes and ward off dogs and other attackers and are still carried in public by many black South Africans for self-defense. Many South African households keep a sjambok.
