Is an Elite Twin Scythe just a metal energy sword?

In an image I remeber seeing a pre-Covenant Sangheili wielding a weapon with a vertical handle and two curved blades.

Now, I remember hearing stuff about ancient Sangheili swords having no contained plasma technology, to they just used to metal blades. I believe the image we see above is one of these blades. Judging by its appearence, I assume this is the Sangheili ‘Twin Scythe’. Is there any more information to clarify this? Also, is there any record of a modern Sangheili using this? You know, like a family heirloom passed down since the Sangheili-San’Shyuum war?

Could be. Nice finding. It could also be a burnblade though if I am not mistaken. Other than speculation though we have nothing else.

if just if they made it available in some maybe an add on to a future halo game like a dlc were you were a sangheili in ancient times it would be extremely amazing just the aspect of sangheilios with the arrival of the sang shyum.
