Sabres are curved, single-edged swords known for their speed and precision, traditionally used in cavalry combat. When purchasing a sabre, consider the blade material—high-carbon steel is ideal for durability and sharpness. Blade length should match your intended use, with shorter blades for close combat and longer ones for more reach. Additionally, consider the historical accuracy if buying for reenactments or display. Quality craftsmanship ensures longevity and performance.
