Elrond`s sword The Hobbit: The Battle of the Five Armies

Might be helpful if you posted a link, because there are several trailers out now, so I have no idea which trailer you're referring to. I also didn't realize Elrond was going to be in Five Armies.

Thanks. As to your question, since we only get such a brief look at it, it's hard to tell whether or not it's a new sword, but I doubt it. The sword glimpsed in the trailer has lines similar to the sword Elrond was seen carrying in An Unexpected Journey, as well as the prologue to Fellowship of the Ring; it also roughly matches the sword provided with LotR action figures of Elrond that I can find on Google.

I think it may just look like a new sword, because this is really the first time we've actually seen it in motion, rather than in a scabbard or being held relatively statically.

I believe it's Hadhafang itself; according to the LotR wiki, Elrond used it in the prologue battle, and it can be seen on his hip in Unexpected Journey. Also, looking at this screenshot of Arwen holding Hadhafang in Fellowship, I'd say there's enough room for it to be used comfortably with two hands (unless you've got meat hooks):

Ok so let me get this straight. Peter Jackson dragged the hobbit out into four movies not three?

No, three films. An Unexpected Journey, The Desolation of Smaug, and The Battle of Five Armies.

Agreed on all counts. I came here after seeing some pictures of the Mirkwood Infantry Sword the other day and that's still at the top of my wishlist, though.

It's Fable Blades, and what you have there is Aphrodite's regret.
That is an early piece i had almost forgotten about.
What is the OAL on that one?

I like some of his other stuff better, but that one still looks pretty good. His work is always fun to look at.
