The Longsword is a type of European sword used during the crusades. Longswords have lengthy cruciform hilts with grips over 15 centimeters, 6 inches, in length, providing room for two hands, straight double edged-blades often over 90 centimeters, 35 inches in length, and weigh typically between 1.2 and 1.4 kilograms, 2 1/2 to 3 pounds, with light specimens just below 1 kilogram, 2 pounds, and heavy specimens just above 2 kilograms, 4 1/2 pounds.

The Longsword is commonly held in combat with both hands, though some may be used single handed. Longswords are used for striking, cutting, and thrusting. The specific offensive purpose of an individual longsword is derived from its physical shape. All parts of the sword are used for offensive purposes, including the pommel and crossguard.
