Darfur-type axes shaped from Trachyte.  Found at Djabarona, 4th - 2nd millennia BC.

The characteristic form of Darfur-type axes is dominated by a broad groove for hafting purposes and a mushroom-shaped or hemispherical neck. It has a sharpened and partly polished cutting edge and it is made of a greenish, fine-grained, homogenous stone (trachyte). Chips on the edges and necks are the result of being used on hard material.
 

Ground axes of the Darfur type are a special feature of Leiterband assemblages. They were probably primarily used for woodworking, but their function as prestige items cannot be excluded. Their distribution is concentrated in the Wadi Howar region and the south-eastern Sahara.
