Baking mud

The demand for our spear heads is increasing, because people always need weapons for self-defence
The sound of hammering rings out across the valley as the team of three blacksmiths fashion arrow heads, spears and jewellery out of the red hot pliable metal.

The workshop is run by Samweli's 60-year-old father, Danieli Kangaga, one of eight sons who all became blacksmiths.
He said in recent years the process has been modernised.
"My grandfather used to make metal by baking the local mud, but now we collect waste metal from around the district. This makes our job easier."
The scrap metal is scavenged at garages, at the local hospital or is found discarded on the ground in the form of broken cooking pots or tin cans.
The Wahunzi blacksmiths have traditionally been considered by their neighbours as lower-class manual workers and are not allowed to marry into other ethnic groups as their work is considered dirty.
But a quirk of location has made them indispensable to the local community.
