Today my PhD advisor gave me this Hadza bow, along with three arrows.
The bow has a pretty hefty draw weight, though I haven't had a chance to measure it yet, it gets very stiff very quickly. The string is twisted giraffe tendon. The tufts of hair come from a warthog. This bow was made by a man who unfortunately was killed by poachers last year.
The arrows are fletched with either vulture feathers or guinea fowl feathers in the traditional hadza fletching style, except for the bird arrow (the one with a simple sharp wood point), which is fletched with whole guinea fowl wing weathers in a style which is growing more popular, especially for small game arrows. It's hard to see here, and I'll get a better picture later, but the vulture fletched ones use a 5 feather fletch, which I've never seen before.
The points are of three major types, and I have one of each here. The plain wooden one is used for shooting birds and dikdiks, and is just resharpened as needed. So, they start long and tend to get shorter over time. This one was snagged by my advisor before it could be used too much. The one with the giant point (middle arrow) is called a "kasama" and it is used for hunting small-medium sized game, basically anything up to a gazelle in size. The barbed point is a poisoned arrow (though the glob of poison has been lost). It also has blood staining the shaft, from a zebra, I think he said. The barbed point is made by cold-forging a 6 inch nail into two separate barbed points. It's pretty awesome.
