A famous dagger found by archeologist Howard Carter in 1925, in the wrapping of Egyptian King Tutankhamun's mummy was made with iron from a meteorite, a study confirms. An analysis of the dagger's blade led by Daniela Comelli, a professor of materials science at the Polytechnic University of Milan in Italy, showed that it contains 10 per cent nickel and 0.6 per cent cobalt. The analysis was conducted using a technique called X-ray fluorescence, which identifies different elements from the characteristic colours of X-ray light they give off when hit with higher-energy X-rays. Then they compared the composition of the dagger's blade with that of 11 metallic meteorites and found it to be very similar. http://www.cbc.ca/news/technology/king-tut-dagger-1.3610539
I'm almost afraid to say anything at all, at this point. Having just said that, I do apologise. I read it earlier today, under the headline "King tut's dagger was from space". I wanted to say something about that but sorry, sorry, apologies for the intrusion and this isn't anything against you, sorry sorry sorry...
The Sword of Goujian Please Register or Log in to view the hidden image! Much more on the king and his sword, here: http://www.sciforums.com/threads/bric-news-comments.84022/page-18#post-2668027 Material: Bronze, but not unifrom. Core of sword is mainly copper and edges have high zink content. It will not break with that core and will not dull with those edges. Very sophisticated metalurgy for that (or any) era! Created: Spring and Autumn period (771 to 403 BC) Discovered: 1965 in Jiangling County Present location: Hubei Provincial Museum, Hubei Province, China The sword was found sheathed in a wooden scabbard finished in black lacquer. The scabbard had an almost air-tight fit with the sword body. Unsheathing the sword revealed an untarnished blade, despite the tomb being soaked in underground water for over 2,000 years.* It is still so sharp that it will cut thru stack of paper! * Possibly 2,700 years but no one knows when it got lost / burried in the mud of a river bank.

He was defeated by a neighboring kingdom and taken captive as a slave for years, but eventually escaped and regained his weakened kingdom. He slowly rebuilt its strength, but while doing so, he ate daily bitter roots and slept on a bed of sticks to remind him, {not let him forget}, his years of captivity. When his kingdom had regained its strength, his army defeated that of the kingdom of his captors. For the modern Chinese, the lesson is clear: Bear what you must, with patience then, when you can, take revenge on those who abused you. The west abused China for decades, even addicting them to opium from India, and divided their nation into separate zones. See map below. China is now growing strong. China may follow King Goujian's example, and extract vengeance on the west for ~100 years of abuse. Please Register or Log in to view the hidden image!

Shanghai's 3D printing expo attracted over 100 companies and 8000 visitors. AFAIK, no one has yet 3D printed a functional sword, but about everything else, including a functional, full size car door has been made during the 3d Chinese 3D exibition, including the doll below.
