The sabre and similar blades such as the cutlass were built more heavily and were more typically used in warfare. Built for slashing and chopping at multiple enemies, often from horseback, the saber's long curved blade and slightly forward weight balance gave it a deadly character all its own on the battlefield. Most sabers also had sharp points and double-edged blades, making them capable of piercing soldier after soldier in a cavalry charge. Sabers continued to see battlefield use until the early 20th century. The US Navy kept tens of thousands of sturdy cutlasses in their armory well into World War II and many were issued to Marines in the Pacific as jungle machetes.
