Apparently, Hollow Ichigo/real Zangetsu's spirit makes up the large blade, while Old Man's spirit makes up the short blade. But we don't know yet if that means the short blade will have Quincy attacks or if it's just Old Man's spirit making it or something.

But I too believe both blades will have various attacks like Getsuga Tenshô and other Zanpakutô-attacks, and his Quincy-powers will only show in the form of the defensive Blut Vene and maybe the offensive Blut Arterie.

I can't refrain from the thought that if Ichigo learns to develop and actively use Blut Vene, he will be like a Shinigami with an Arrancar's Hierro.
