The design and length of longswords varied between cultures and can even vary within the same culture depending upon the era. However, the length of longswords generally ranged between 35 to 47 inches (0.89 to 1.2 meters).
Most longswords have a double-edged blade, though some have a single-edged blade, with a sharp point at their tip. They often have grooves known as “fullers” that run the length of their blade, one on each surface, that make the blade both lighter and more flexible.
Most long swords had an ovaloid metal plate between the blade’s base and grip, protecting the latter from getting damaged against the metal in the mouth of a sheath, in addition to offering the user’s hand some protection. A second plate of metal, either circular or ovaloid in shape, would also be fitted on to the pommel.
