Carbon nanotechnology in an 17th century damascus sword

Interesting article about Wootz damascus steel at:

Some of the remarks in the comment section will make you wonder about some people...

Not really surprised with the nanotubes - since blacksmiths and kilns have generated carbon Buckey Balls.
A number of years ago it was shown in the blacksmith stove pipes in old Tuscon Arizona.
But these are complex nano tubes. Interesting.

Here's another site about a guy named Greg Orbach who tried his hand at replicating Wootz steel

Greg did an impressive demo for us (Maritime Blacksmiths) this past spring. Made a nice little Wootz buiscuit while we watched. Some pics at:

But he used scrap iron, not magic ore from India. I don't know if he or anyone has done serious metallographs or similar studies of his product to compare with the 17th c. specimen in which Marianne Reibold claims to have found carbon nanotubes.
