dragonslayer_(sword)

"That thing was too big to be called a sword. Too big, too thick, too heavy and too rough. It was more like a large hunk of Iron."

The Dragonslayer is a gigantic greatsword primarily wielded by Guts (berserk) of Berserk. Forged by the blacksmith Godot for a royal contest among blacksmiths to forge a sword capable of killing a dragon, it is Guts's primary weapon against the demonic Apostles of the God Hand as the Black Swordsman.
