I am in awe... there are so many real examples of clubs I have only seen sketches of. This is amazing.
Well, I can't possibly show that sort of volume... but, I got a Yanomamö dueling club recently. It, like most things made by them, are made of natural materials, with no decor, and relatively simple but effective. You can see them briefly in the famous "Axe fight" scene,
here. They began fighting with roof poles, and normally would have escalated to a club duel with these wooden-sword/shortstaff style clubs... but it escalated right into an ax/machete fight.
These are incredibly rare in collections, I know of only 2, mine and the one in the American Museum of Natural History.
