Yemenis have proved the old age saying "fire is the test of gold; adversity, of strong men" right. Thousands of deadly airstrikes are pounding Yemen by the Saudi-led coalition which is fighting Houthi rebels but killing thousands of civilians. In most cases, jets drop US-made munitions. While some bury their dead, others rush to the sites of the airstrikes to collect the valuable fragments of the missiles. Over fire and with hammers, Yemeni blacksmiths turn the fragments into daggers or Jambiyya. The daggers are curved sword like hooks and they are part of the Yemeni traditional attire. The blade is made of steel and the shape of the hilt often refers to the region or the tribe of its bearer. The price also depends on whether the hilt is made out of wood, buffalo horn, or Rhinoceros horns. The most expensive Jambiyya is the one with a horn hilt, of thousands of dollars.
