Description: A spear made to be thrown
Profile: Originally a throwing type spear, it was used in the past by throwing it to the skies to attack distant enemies. However, when bows were made easier to use, their role as a long-distance weapon was abolished due to difficulties such as cost and difficulty of transport. Since they used to be made disposable, their manufacture is well ordered and in the present they are used as practice weapons.
