African Throwing Knives are something about which I know nothing, and in which I have no interest at all, however I know some people do find them of iinterest.
The following book has just been published:-
THE CUTTING EDGE. WEST CENTRAL AFRICAN 19TH CENTURY THROWING KNIVES IN THE NATIONAL MUSEUM OF ETHNOLOGY - LEIDEN by A.M. Schmidt and P. Westerdijk.
This publication describes and shows one of the oldest collections of African throwing knives from West Central Africa (Congo) now housed in the National Museum of Ethnology in Leiden, The Netherlands.
The catalogue offers an insight into the diversity of the collection and its fascinating 19th century history.
