hittites contributions to weapon making

What were some contributions of the Hittites?

The Hittites may have been among the first irons to use as a precious metal in such things as thrones and ceremonial daggers work. There is no evidence that they know how to produce steel cheaply enough, and make it hard enough to use as weapons of war.

The most important contribution is the Hittites modern history. Hittite diplomatic tablets rather long preamble about negotiations that had gone before, and are part of the history of relations between Hatti and other nations.
