The Sharp Sword of the world's most Apparently Not Katana

People are definitely a lot of thought if the sharpest sword in the world is a samurai from japan, you are wrong turns eiits sharpest sword is the sword of Damascus (Damascus Sword) ..The following is a little explanation:
Damascus swords are very strong but still flexible so it can bend the tip of his sword to the sword hilt. It is also very sharp sword that can cut European sword with ease, even said to be able to cut a piece of silk that was dropped to the ground. Typical characteristics are the Damascus Sword Pattern / Pattern Watermark surface, similar to the Keris Indonesia / Japan Sword (however Watermark on the Steel Damascus not because of technical metal folds).
Research conducted by a group of scientists from the University of Dresden, reveal an extraordinary secret-existence of carbon nanotubes. Apparently without realizing it, the maker of this sword uses nano technology while forging a sword. Unfortunately, the technique of making this sword disappeared in the 18th century.
Nanotechnology encompasses technology development in the nanometer scale, usually 0.1 to 100 nm (nanometer equals one thousandth of a micrometer or one millionth of a millimeter). The term is sometimes applied to very small technology. Also very broad in scope, can be extended to various fields such as medicine, robotics, physics, etc.. While carbon nanotubes are cylindrical carbon bond with a diameter of 4 nanometers (1 nano = 1/1.000.000.000).
Material used is called wootz steel, rich in carbon nanotubes. Materials are said to be imported from India, and the manufacture Damascus swords halted due to expiration of this material.
Legendary Damascus steel is the material of steel that have superplastic properties (the ability to experience permanent deformation without cracking up to 1000%).
With these unique properties of Damascus steel is widely used as material for making swords and guns. According to the myth that guns are made using Damascus steel will never blunt or broken. Besides having superplastic properties of Damascus steel also has a pattern that is characteristic of water (watermarking) on ​​its surface.
Damascus steel was first made in India and then progressed to Syria. Damascus own name given by Western nations involved Crusades and found weapons made from Damascus steel in the city of Damascus, Syria.
Damascus sword once used by the Muslim leader Salahuddin al-Ayyubi the Third Crusade against the Christian army led Richard the Lion Be .. The two leadersmutual respect. The two leaders who later became a legend, who want to see please watch the movie Kingdom of Heaven (2005)
