hard to tell from the picture, Any info on the overall length, and close-ups of the head especially where it narrows to the tang would help. The small 'head' at the lower end may just be a ground spike to protect the end and counterbalance the main striking end. given the long exposed tang section, without more info I suspect it's a light throwing spear that could be from anywhere in Africa.
I also gather 'Hurling' is described as Organised warfare with clubs, somewhere between war and murder. The sticks are very close to what the Pacific islanders use for mortal combat. I hear actually hitting the sliotar (ball) is purely coincidental.
A combat related discussion on the subject was posted (by someone close to me)
