it does 9 armornegating nostrength added damage. So you will always deal 9 damage if you hit regardless of strength and armor.

Reasoning behind this is that it´s sort of an ethereal blade(hence the name wraith sword) that has a life of its own, so armor offers no protection, but you can´t swing it harder with your strength.

So it´s a good weapon vs SCs/Thugs with high protection, but pretty useless vs masses of troops. The damage might be a bit low, maybe 12 damage would be a better value.
