Sword

Bronze Age

Main article: Bronze Age sword

Humans have manufactured and used metal bladed weapons from the Bronze Age onwards. The sword developed from the dagger when the construction of longer blades became possible, from the late 3rd millennium BC in the middle-east, first in arsenic copper, then in tin-bronze. The oldest sword-like weapons are found at Arslantepe, Turkey, and date to around 3300 BC. It's however believed that these are longer daggers, and not the first ancestors of swords. Swords longer than 90 cm were rare and not practical during the Bronze Age as this length exceeds the tensile strength of bronze, which means such long swords would bend easily. It was not until the development of stronger alloys such as steel that longswords became practical for combat.

The hilt, either from organic materials or bronze (the latter often highly decorated with spiral patterns, for example), at first simply allowed a firm grip and prevented the hand from slipping onto the blade when executing a thrust or the blade flying out of the hand in a cut. Some of the early swords typically had long and slender shaped blades intended for thrusting. Later swords were broader and were both cutting and thrusting weapons. A typical variant for European swords is the leaf-shaped blade, which was most common in North-West Europe at the end of the Bronze Age, in the UK and Ireland in particular. The Naue Type II Swords which spread from Southern Europe into the Mediterranean, have been linked by Robert Drews with the Late Bronze Age collapse.[1]

Sword production in China is attested from the Bronze Age Shang Dynasty. The technology for bronze swords reached its high point during the Warring States period and Qin Dynasty. Amongst the Warring States period swords, some unique technologies were used, such as casting high tin edges over softer, lower tin cores, or the application of diamond shaped patterns on the blade (see sword of Goujian). Also unique for Chinese bronzes is the consistent use of high tin bronze (17-21% tin) which is very hard and breaks if stressed too far, whereas other cultures preferred lower tin bronze (usually 10%), which bends if stressed too far. Although iron swords were made alongside bronze, it wasn't until the early Han period that iron completely replaced bronze.

The earliest available Bronze age swords of copper discovered from the Harappan sites date back to 2300 BC. Swords have been recovered in archaeological findings throughout the Ganges-Jamuna Doab region of India, consisting of bronze but more commonly copper.[2] Diverse specimens have been discovered in Fatehgarh, where there are several varieties of hilt.[2] These swords have been variously dated to periods between 1700-1400 BCE, but were probably used more extensively during the opening centuries of the 1st millennium BCE.[2]

Not every culture that used bronze also developed swords. For example, the steppe tribes preferred short daggers (the akinakes). In South America, bronze was used by the Incas, and although the concept of the sword was known in the form of wooden swords with stone edges (the macahuitl), they did not develop bronze swords.
