Middle Eastern Supertechnology

Tech level twelve, I believe!

This is pretty cool, discovering that carbon nanotubes, the "technology of the future", has been used in weapons of warfare for nearly two thousand years. For those who don't know, Damascus Steel is renowned throughout the world for being super-top-quality blades, rivalling the Japanese swordsmiths of the age, as well as having the cool dark and white banded stripes all over the metal that has never been duplicated. True Damascus manufacturing was lost in the 1800's, so a dozen ways have been made to make SIMILAR blades, but never the real thing. But this latest clue, the carbon-nanotube-filled-blades may have uncovered the final key.

TIME TRAVELLING TERRORISTS!

Or, you know, excellent metallurgists. Whatever.
