sentences:  The bronze axehead, made by casting, was at first similar to its stone predecessors but then developed a socket for the wooden handle to fit into, and a small loop or ring to make lashing the two together easier.Groups of unused axes are often found together, suggesting ritual deposits to some, though many archaeologists believe that elite groups collected bronze items, perhaps restricting their use among the wider population.Bronze swords of a graceful "leaf" shape, swelling gently from the handle before coming to a tip, have been found in considerable numbers, along with spear heads and arrow points.
