The Vorpal Blade.

This mod will add the Sharp Sword to the game, which is a legendary Daedric artifact and has unique abilities. You can find this sword in the northwestern part of the trembling islands, in the Tea Party location.

This sword has a special enchantment that summons a copy of it and allows you to fight with two swords at the same time.

The mod requires the Shivering Isles DLC to be installed.
