What is the defining characteristic of a longbow?

The defining characteristic of a longbow is that it has straight limbs that arc when strung. This design allows for a significant level of energy storage, which can translate into greater velocity and distance when the bow is drawn and released. The straight limbs are a fundamental feature, distinguishing longbows from other types of bows, such as recurve bows, which have a more pronounced curve even when unstrung.

Additionally, longbows are traditionally crafted from a single piece of wood, maintaining their characteristic straight profile, and rely on their simplicity and efficiency in construction and use. This structure also contributes to the bow's ability to perform well under various conditions, making it a popular choice among traditional archers. Other options, such as those involving composite materials or specialized sighting systems, do not define the traditional longbow and apply more appropriately to other types of bow designs.
