What's with that new Sith Lightsaber seen in the Episode VII teaser?

I happen to find the design quite appealing! The "renovated" rendition that's been displayed is fantastic with regards to functionality, however! :)

My nerd buddies assured me it's actually an extended universe lightsaber called a "flame saber". Also, I am assured that users cannot get harmed, because they use the "force" they can't get cut by their own weapon. I was also told the shape cannot be changed like that, because of the way the crystals work in a light saber. If I garner any other pearls of wisdom I shall share them here with you all. 

SVANYA - Hahaha! That "dead horse" animation is superb! :)

I think what we need to do is WAIT FOR THE FILM TO COME OUT TO FIND OUT WHY THAT LIGHTSABER LOOKS LIKE THAT...THERE IS A REASON THAT I WISH I COULD SHARE BUT DON'T WANT TO RISK BEING SUED.

I love that Lightsaber. It reminds me alot if longswords, which is awesome!

I don't really have a problem with it. I'd just assume the Jedis and Siths that used it were trained with how to maximize it's efficiency similar to those that are trained to dual wield and used the double bladed lightsabers.

People who are crying about the saber need to get a life.

It is a symbol, likely to evoke the audience to think of the cross, sacrifice, religion (Christianity), and the idea that this is an ancient weapon (medieval), or also imply an ancient feud, etc. I'm sure J.J. knows the design is very impractical; however, a properly designed version would not convey anything (or it lacks the required visual power).

Thanks Chris!

Sawa;)

I'm fine with the design.  I hope they treat it like a two-handed claymore because that would be interesting to see with a lightsaber.

I don't have a problem with it, but I prefer a typical lightsaber. Not a huge fan of it :/

OKAY SO WE ALL KNOW BY NOW ABOUT THE "CROSSGUARD LIGHTSABER". BUT A GOOD SOURCE TOLD ME IT'S NOT A TRUE LIGHTSABER AFTER ALL. IT IS LIKE WE'VE HEARD, AN ANCIENT SABER TECHNOLOGY. AND IT DOES HAVE A CRYSTAL IN IT. BUT!!!!! THE SABERS MAIN POWER SOURCE IS NOT THE CRYSTAL, BUT THE USER HIM/HER SELF. THE SABER FUNCTIONS WITH THE POWER OF THE FORCE, LIGHT/DARK. AND HARNESSES THE ENERGY OF THE FORCE!!!!! AND THE SABER IS SAID TO BE SO POWERFUL, SUCH RAW ENERGY, THAT A NORMAL SABER WOULD NOT EVEN BE ABLE TO WITHSTAND A BLOW FROM THIS ANCIENT WEAPON!!!!! THAT IS WHY IN THE TEASER THE BLADE LOOKS RAW OR VERY UNSTABLE. AND IT ALSO KIND OF CONFIRMS THAT THE TWO MINI HILTS AT THE BOTTOM MAY BE EXHAUST PORTS AFTER ALL. COMMENT BELOW, LET ME KNOW WHAT YOU THINK!!!!!!!!

It's Narcil, Sword of Gondor's King Elessar!  No seiously I like the design.
