The sword that conquered the world.
Gladii were two-edged for cutting and had a tapered point for stabbing during thrusting. A solid grip was provided by a knobbed hilt added on, possibly with ridges for the fingers. Blade strength was achieved by welding together strips, in which case the sword had a channel down the center, or by fashioning a single piece of high-carbon steel, rhomboidal in cross-section. The owner’s name was often engraved or punched on the blade.
A fully equipped Roman legionary was armed with a shield (scutum), several javelins (pila), a sword (gladius), often a dagger (pugio), and perhaps darts (plumbatae). Conventionally, the javelins would be thrown to disable shields of enemies before engaging the enemy, at which point the gladius would be drawn. The soldier generally led with his shield and thrust with his sword. All types of gladius appear to have also been suitable for cutting and chopping motions as well as for thrusting
