Why not show more African axes. These weapons are rarely seen on the forum.
First two axes from the Mende-tribe in Sierra Leone :
Second picture is of two Songye axes from Congo
The third pic is my best axe. Again from the Songye tribe. All three these axes have a handle covered in monitor skin. This piece is huge : the cutting edge measures 39 cm. The blade weighs about 2 kgs.
Nice detail are the heads carved in the axe blade. In this case, there are 42 small heads.
Tim, about your axes : the first one is definitively South African (Zulu or Swazi). The others perhaps from the Tschwana (Botswana) or the Mangwato (I've seen an example in the book from Fischer & Zirngibl).
