"Cimpaaba" were used among the Woyo of Cabinda WOOD (Angola) and Congo-Kinshasa, as well as among the Kakongo, the Lingi, and the Vili.

They were part of the regalia of a tribal chief and were a symbol of his authority. An emissary entrusted with the "cimpaaba" of a tribal chief spoke with the authority of the latter.

Several authors mention that "cimpaaba" played an important part in trials. Even the mere display of the sceptre knife could silence heated debates. The use of the "cimpaaba" was associated with certain codes. The way in which a "cimpaaba" was held or placed on the ground during palavers, provided information about the imposition of a sentence, or the support for or opposition against one party or another.WOOD
