Central African throwing sick/club?

[Tim Simmons]

I just realised there is this example in Waffen aus Zentral-Afrika, Museum fur Volkerkunde. From the Fali N,E Congo. Quite when a dance stick becomes a club is anyone's guess. I do not know if this club has any throwing properties. The use of a club in dance would be a good method of training basic moves. Many training systems involve synchronized repeated set moves.
