Days of Future Past Random Question - Azazel's weaponry

[Nerial]

Hi, everyone. Does anyone know the weaponry (specificially, the type of sword) that Azazel uses in XM:FC? I'm writing a fan fiction and can't figure it out.

Thanks in advance! t:

No idea about the type, but I believe there is some concept art of them floating around.
