Dragon Handle

Meliodas' broken sword or the Dragon Handle is his primary weapon, as he no longer possesses his sacred treasure after selling it for money for the Boar Hat. Useless as a weapon in itself, Meliodas uses it in conjunction with his ability, Full Counter.

Appearance
This sword, as its name suggests, includes a broken blade, and a unique hilt. Its hilt's other end has the design of a dragon's head, with three spikes above it, with another handle, whose end has the design of a claw of the dragon's.

Background
The hilt of the sword, the other end of which has what appears to be a dragon's head, is a fragment of the Coffin of Eternal Darkness, and a key to the revival of the Demon Clan, making it a part of Hendrickson's plot to resurrect the clan and start the Holy War.

History
Having acquired it through unknown means, Meliodas has, according to Ban, never let go of this broken sword since joining Seven Deadly Sins. Once, when the group of knights hadn't yet been disbanded before the betrayal, Ban, puzzled by his captain never letting go of the weapon, tried to learn more about it, and then, steal it, but was then given a lasting wound by the Dragon's Sin of Wrath using the sword and Enchantment: Hellblaze, the wound not having healed despite his regenerative abilities. Much later, in Dalmary Town, Meliodas, having been fatally poisoned by Dana earlier, suddenly regained consciousness when Golgius of the Weird Fangs tried to grab the sword from his hand, releasing an aura powerful enough to scare the Holy Knight. He declared that he would not let go of the object even if he dies, and that this was the only way he could atone for his sins. His eyes were mysteriously colored jet black, with a strange symbol present on his forehead.

When Oslo blocked their way to the entrance of the Capital of the Dead, Meliodas, stopping Ban from killing Oslo, slightly unsheathed his sword, and created an immensely huge ethereal dragon-like creature, that resembled the dragon on the sword's hilt, to scare the creature. It also seemed to be visible only to the Black Hound. The sword was stolen by Helbram, during the attack of the Holy Knights in Byzel, who detached the damaged blade from the hilt, and revealed the fact that the hilt was a key to the revival of the Demon Clan.

Abilities
The hilt of the sword, the fragment of the Coffin of Eternal Darkness, displayed the ability to create an immensely huge ethereal dragon-like creature, that resembles the dragon on the other side of the hilt, and seems to be visible only to the victim. It was reveal that the Broken Sword has the power to open the gate to the Demon realm, but only a little.
