A sword is a kind of sharp weapon that has a long blade. Swords can have two sharp edges or only one sharp edge. In some cultures, when compared to other weapons, the sword usually has more prestige or the highest.

The blade of the sword is usually made of a hard metal such as iron or steel. Even though there was a sword of gold, it was only used as decoration. For practice, a wooden sword is usually used, although a hard wooden sword is still dangerous. Weapons such as swords and spears that use obsidian blades were used by indigenous tribes of Central America and South America who at the time of European colonization did not know metal.
