Stick from Congo, fighting stick

[Congoblades]

This is a stick completely covered with decorated copperbands, stick is almost 2 meters long, in the middle you can see what is left of a handle in textiel. On the top of the stick there is a metal wire, on the bottom a metal point like used on spears. I have no idee what it is used for... but like to know. I found some info about stickfighting but those were completely different sticks.
