You mean umshlanga!
Here is the a picture of an isiJula showing the cow tail binding method binding a Zulu spear.
I have this iKlwa with a woven rattan binding.
I have another iKlwa that is very old that came from a thatched roof that has just leather wrapping.
This last one is an awesome blade and I would not feel uncomfortable saying this may, may be a Shaka era blade.
Freddy, would you know if that museum has a similar book on
Southern Africa?
