Indigenous culture of a native Amazonian people.  The Matis leader Binan Tucum demonstrating how to make fire using a drill and fireboard. When hunting, the Matis always carry a drill and fireboard in their blowgun quiver together with poison tipped darts.  Getting a fire started in a wet environment such as the Amazon Rainforest can be quite the feat after it rained all night, the night before; which is exactly what happened before this photo session.  Note his close-cropped hair that is typical of both male and female members of this South American tribe.
