Usable as both a Garrote and a stabbing weapon. You don't remember that altercation between me and a Tragic the Blathering player at Wizards that one time? The one where Ricky used the power of Girth to interpose himself between me and the Tragic player after he started a fight with me?
Nothing says class like a sword. Personally I enjoy a curved blade, there is just something about the flowing nature of curved lines...anyway. I voted scimitar, but really any type of sword makes me happy.
