A sword is a bladed weapon intended for both cutting and thrusting. The precise definition of the term varies with the historical epoch or the geographical region under consideration. A sword in the most narrow sense consists of a straight blade with two edges and a hilt, but depending on context, the term is also often used to refer to bladed weapons with a single edge (also referred to as a backsword).
