And the next step...
In another thread I mentioned on a spear buying trip, my wife took it upon herself to liquidate my on hand cash and buy some knobkerries.
Here is one she bought. It is 38 inches long'
Do you see it in the picture? It's not a knobkerrie at all. It is the stick for a shield. If this stick is for a shield it may be for a iHubelo or hunting shield or an umBumbuluso or Cetshwayo War shield.
