The Axe (オノ Ono), also known as Hatchet and Big Axe, misnamed as Scythe (大鎌) in the PC Engine manual, is a weapon from the series that is mostly thrown in a 45 degree angle.
The normal Axe is able to penetrate through objects, but it cannot be thrown consistently.
The normal Axe is a loop to loop foward like weapon. Confusing to use at first, but strong.
With the Golden Armor Arthur can also use the Lightning Magic (雷光の魔法). It releases energy beams in several directions.
The axe is a strong weapon that can pass by obstacles, but it has a short range and is slow, Arthur being able to thrown only one at a time and Lancelot two at a time. They can use its magic with the powerful armor.
