Sword

A sword is a bladed weapon intended for slashing or thrusting. The precise definition of the term varies with the historical epoch or the geographical region under consideration.

Non-European weapons called "sword" include single-edged weapons such as the Middle Eastern scimitar, the Chinese dao and the related Japanese katana. The Chinese jian is an example of a non-European double-edged straightsword, like the European models derived from the double-edged Iron Age sword.

A sword consists of a long blade attached to a hilt. The blade can be straight or curved.
Thrusting swords have a pointed tip on the blade, and tend to be straighter; slashing swords have a sharpened cutting edge on one or both sides of the blade, and are more likely to be curved. Many swords are designed for both thrusting and slashing.
