The estoc sword remains unique amongst the swords due to its stiff, narrow, and sharply tapered blade designed almost entirely for thrusting. Unlike cutting swords, the estoc excelled at piercing gaps in heavy armor during the medieval period. Its lack of sharpened edges emphasized precision, control, and armor penetration. Favored by knights in late medieval warfare, the estoc bridged the gap between traditional swords and specialized anti-armor weapons, securing its distinct place in sword history.
