European swords originated in the Bronze Age, with their development spurred by the widespread adoption of heat-treated steel technology after the 10th century. Medieval swords primarily included straight-bladed, double-hilted longswords, suitable for one- or two-handed use; and knight’s swords designed specifically for mounted combat, with triangular blades ideal for thrusting. The Renaissance saw the emergence of lightweight, slender, and swift swords, primarily used for thrusting. The Scottish broadsword, exceeding 1.5 meters in length, was renowned for its powerful slashing and chopping capabilities. With the rise of firearms, swords gradually transitioned into sidearms and ceremonial implements.
