What's with africans and their love of fachions/machetes?
well you can't find a better tool for chopping through the jungle like through a bunch of tutsis.
The rainforest was always the least densely populated area of the continent aside from the desert. It's full of disease and there's no food.
Most niger-congo speakers (aside from pygmies) are scared shitless of forests anyway. In one bantu language "nightmare" translates as "the jungle is approaching".
it's the best weapon to chop jungle foliage, wild animals and rival tribe's arms
Same reason that short, broad weapons were popular in the bronze age up til the Romans, they were easy to use and didnt require the wacky wild swordplay that larger and thinner swords required
