The sure sign of someone who is either new to all of our discussions, or wasn't paying any attention...

Yes, aura beams. Also called aura slashes/waves/pulses. A technique used by characters with fine levels of Aura control, which allows them to extend the Aura they have placed around their weapon in different ways, to effectively increase attack range, damage, and versatility. Examples are frequently seen throughout the show, but the most frequently used one I've seen is Blake. She regularly discreetly uses Aura beams, such as when she was able to cut away her train carriage in her trailer despite her sword being nowhere near the connecting line it was cutting, and later on when she was assaulting a Nevermore's back as it was flying. And again when she was fighting Roman.

Do note that this merely increases weapon range somewhat beyond the norm. It does not make your sword suddenly able to stab someone from across the hall via extending energy blade.
