The first sword in human history was likely constructed by early civilizations during the Bronze Age, around 3000 BCE. It is challenging to attribute the creation of the very first sword to a specific individual, as the development of swords was a gradual process influenced by various cultures and regions.

Early swords were typically made from materials such as stone, bone, or wood. Over time, as metalworking techniques developed, swords began to be forged from copper, bronze, and eventually iron.

Different ancient cultures independently developed their own methods of sword construction. For example, ancient Egyptians crafted swords from bronze and iron, while the Greeks produced swords known as xiphos and kopis. Mesopotamians, Persians, Chinese, and many other civilizations also developed their unique sword-making techniques and styles.

It is important to note that the construction of the first sword predates recorded history, so the specific details of who built the very first sword have been lost to time. The forging of the first sword can be seen as a collective achievement of early human societies as they advanced from simple tools to more sophisticated weaponry.
