A strip of the animal's hide is cut and carved into a strip 3 to 5 feet (0.9 to 1.5 m) long, tapering from about 1 inch (25 mm) thick at the handle to about 3/8” (9 mm) at the tip. This strip is then rolled (possibly between heavy metal plates) until reaching a near circular form. The resulting whip is as flexible as whalebone, and very tough. A plastic version was made for the South African Police Service, and used for riot control.
The sjambok had a variety of uses, with the most obvious being cattle driving. While it may have been synonymous with slave discipline, 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 actually illegal to use in South Africa due to their historic connotations. The sjambok is also used today in South Africa by those who mete out discipline imposed by kangaroo courts.
The instrument is also known as imvubu (hippopotamus in Zulu), kiboko (hippopotamus in Swahili) and as mnigolo in Malinké. In the Portuguese African colonies and Congo Free State it was called a chicotte, from the Portuguese word for whip. There it was sometimes rendered even more lacerating by adding nails.
In the Belgian Congo, the instrument was also known as fimbo and was used to force labour from local people through flogging, sometimes to death. The official tariff for punishment in this case was lowered in time from twenty strokes to eight, then (in 1949) six, and progressively four and two, until flogging was outlawed completely in 1955. In North Africa, particularly Egypt, the whip was called a kurbash, after the Arabic for whip.
