The closest equivalent of a working serrated sword in real life would be the zulfiqar tegha, a dual bladed weapon. This design has been suggested in real life, but is impractical because the serration weakens the blade, making it prone to break right in the areas you would put the most stress. The shape of this blade is very unique, with ridges along it's entire length, probably to work like fish hooks.However, acquiring the Berserker Blade also requires that the player be a member of the Bell Keepers covenant, as the phantom will. It is dropped by the Mad Warrior that uncommonly spawns (resting at a bonfire a few times should cause it to respawn). The Berserker Blade can be found in Belfry Sol. The Berserker Blade is a katana in Dark Souls II.

This sword, likely shares an archetype with Chaos Platemail due to both items involving chaos in their names. For the Dark Souls III variant, see Black Blade.It may be a reference to the God of War Blades of Chaos or FromSoftware's Dark Souls' Chaos Blade.The Chaos Blade has an identical cross-guard as the Scarlet Katana.When upgraded to +15, it does 1,500 damage. It has a 12% critical chance and deals 938 damage. The Chaos Blade is a rare level 82 longsword, dropped from the Undead Warrior in Va' Rok. While this weapon was forged, shards of Chaos Platemail fell into the mixing vat of metal, giving this weapon its power.
