Answer:
iron
Step-by-step explanation:
Around the 12th century BCE, the Hittite craftsmen in Anatolia, which is a place around eastern Greek and Western Asia, were known to be involved in ironworks or ironsmiths. This led to the formation of series of creating tools and weapons made of iron.
Also, this period is considered to be the beginning of the Iron Age, as humans moved away from Bronze age.
Hence, it can be concluded that By about 1200 BCE Hittite craftsmen in Anatolia had developed techniques for making weapons of IRON which proved to be both stronger and cheaper than bronze and became the most important metal for making weapons and tools.
