Right and left side of the same sword.
A black and white (cool 
) sword with a green energy thing in it.
If there’s one thing I have to say is that it doesn’t really look like a sword. You could stab someone with it, yes, and you could hurt them with those spikes, but it doesn’t seem very functional. First of all, it looks really heavy. Second, there’s no edge, so you can’t cut with it. Of course, I understand it is fantasy, but it just doesn’t look like a sword in my opinion. More like a bludgeoning/stabbing weapon. It looks kinda neat, though
