Honorblade of Chorrol

The Honorblade of Chorrol is a non-magical sword obtained from a Redguard Valley Ogre Chieftan in the quest Sins of the Father, or by pickpocketing the Countess of Chorrol while she sleeps after completion of the quest. It has 27 damage, depending on your level. and no weight (because it's a quest item), making it an ideal melee weapon. Although it is not enchanted, its damage is considered magical (foes hit by the blade will glow) and can hit monsters such as ghosts that are normally immune from normal damage.
