A real katana, which is a traditional Japanese sword, typically weighs around 2.2 to 3.3 pounds (1 to 1.5 kilograms). The weight of a katana can vary depending on factors such as the specific design, craftsmanship, and materials used.

A well-made katana is carefully balanced to provide optimal handling, maneuverability, and cutting performance. The weight distribution is designed to allow for precise control and fluid movements in combat.

The weight of a katana is primarily concentrated in the blade, which is typically made of a combination of hard and soft steel to achieve a balance of strength, flexibility, and sharpness. The tang (the part of the blade that extends into the handle) and the fittings, such as the guard and handle, also contribute to the overall weight.

It's important to note that the weight of an individual katana can vary slightly depending on factors such as the length and thickness of the blade, the type of steel used, and the specific craftsmanship of the swordsmith. Additionally, the preferences of the sword owner or collector can also influence the weight of a katana, as some individuals may prefer a slightly lighter or heavier sword based on their intended use or personal preferences.

In summary, a real katana typically weighs around 2.2 to 3.3 pounds (1 to 1.5 kilograms). The specific weight can vary depending on the design, craftsmanship, materials used, and individual preferences of the sword owner or collector.
