The weight of an average broadsword can vary depending on its specific design, historical period, and regional variations. Broadly speaking, a typical broadsword can weigh anywhere from 2 to 5 pounds (0.9 to 2.3 kilograms).

Historically, broadswords were used in various cultures, and the weight of the sword could differ based on regional preferences and the intended use of the weapon. For example, European broadswords, such as the Scottish claymore or the English basket-hilted broadsword, tended to be on the heavier side, often weighing between 4 to 5 pounds (1.8 to 2.3 kilograms) or more. These swords were designed to be wielded with two hands and were used primarily for cutting and slashing attacks.

On the other hand, broadswords used in other cultures, such as the Chinese dadao or the Indian talwar, could be lighter, typically weighing around 2 to 3 pounds (0.9 to 1.4 kilograms). These swords often had a single-edged blade and were known for their agility and versatility in combat.

It's important to note that the weight of a broadsword can also vary based on individual variations and specific historical examples. The weights provided here are general ranges and should not be considered definitive for all broadswords.

In summary, the weight of an average broadsword can range from 2 to 5 pounds (0.9 to 2.3 kilograms), depending on its design, historical period, and cultural context. European broadswords tended to be heavier, while those from other cultures could be lighter. Individual variations and specific historical examples can also affect the weight of a broadsword.
