Damaskus sword

Damascus's sword is a very well-known sword both among Muslims and non-Muslims, since the Crusades. This sword was produced from the 12th century to the 18th century. In the heyday of Islam it has found a very high metallurgical technique with the presence of the Damascus sword at the time of the Crusade which was quite astonishing to the European side at the time. According to National Geographic, a study conducted on the damascus sword reveals that the sword contains nanowires, carbon nanotubes (CNTs), and other micro materials. Such a complex structure may explain why the sword can become very sharp.

The History of the Sword of Damascus
This Damascus sword is a sword used by Salahuddin Ayyubi also known as Saladin, the leader of Kurdish Muslim fighters from Tikrit. Based on the legend, it is mentioned that the sword belongs to Salahuddin Ayyubi is very sharp and became one of the key victories of Muslim troops he led in the

Crusades.
This sword is made from a hard but flexible material because it has carbon nanotubes. Damascus sword compilers include unique material because it includes superplastic material, which is material that can be deformed several times without cracking. However, despite its tremendous elasticity the basic material of the damascus sword also includes materials

that have considerable hardness. The raw material of the damascus sword is known as wootz steel. This wootz steel originated from areas in India and Sri Lanka, which were then sent to Syria to be forged into a damascus sword. From the 3rd century to the 17th century, India has sent steel ore to the Middle East. Wootz steel also contains molybdenum and vanadium.
In the historical record, damascus steel was first developed by the Indians (precisely the South of India), which then the technology of its manufacture was taught to the Middle East, developed for the swordmaking. The damascus sword has a flowing water pattern that characterizes the sword. The origin of the name of the sword is still uncertain, one of the existing theories reveals that the origin of the name is derived from the similarity of the sword with Damask fiber.
In Russia, developed round steel is used for strong weapons-making materials, including swords, knives, and axes. Tsar Michael from Russia used a helmet made of round steel in 1621. The origin and manufacture of the round steel is not known for certain, but there are indications that round steel in Russia originates from Persia and Turkestan. There is a resemblance to damascus steel with round steel. In the 19th century, Pavel Petrovich Anosov made several attempts to make the work.
