The sabre or saber is a kind of backsword that usually has a curved, single-edged blade and a rather large hand guard, covering the knuckles of the hand as well as the thumb and forefinger. Although sabres are typically thought of as curved-bladed slashing weapons, those used by the world's heavy cavalry often had straight and even double-edged blades more suitable for thrusting. The length of sabres varied, and most were carried in a scabbard hanging from a shoulder belt known as a baldric or from a waist-mounted sword belt.
