Wootz steel - a form of highly durable carbon steel was a specialty of ancient India, and much sought-after in the West. In Roman literature there are references to the import of this steel from the Chera country of southern India.
Another sign that Ancient India was celebrated for its steel is seen in a Persian phrase - “giving an Indian answer” which means “a cut with an Indian sword”. Wootz steel was widely exported and traded throughout ancient Europe and the Arab world.
The word wootz is an anglicised version of urukke, the word for melting in Tamil and Malayalam, OR urukku or ukku the word for steel in Kannada and Telugu.
