Two more boys from Brazil. Interesting sword club. The other is a hefty 1.698KG and 97cm long, 7x6cm at the distal end. They came with labels that suggested Tapirape/Karaja from the Island of Bananal. Also similar to others I have that were labeled Karaja/Kayapo. There are subtle differences when under close inspection but whether there is identifying relevance I do not know. I would think it much like weapons from people in the Congo- the same or very similar designs and forms are seen in the various surrounding tribal groups. Interesting link help set the stage.
