It's one-hand and it's not unique. A shadow priest in my guild said he wanted to learn dual-wield in order to have it in both main hand and off-hand. ^o^
Dual-wielding with this might not give the best melee dps. But if I have a enchancement shaman raiding Black Temple, I will want it just for the look and because I can have it. Main hand Hammer of Judgement and off-hand this sword would work too.
Probably Blizzard will change that to main hand soon, since it's probably a mistake or a typo or to spoil the fun.
