Signum sees an opening, if only just. She brings her sword and scabbard up in a cross to stop his chainsword, not caring in the least what it might do if it got through that defense - it simply will not. Matching his gaze, she proceeds to give a hard, straight kick to the other knight's chest to break his momentum and, should she break the bind like that, to whip her sword loose and whirl it just far enough to scratch the tip of his nose.

Hopefully that would draw blood and end the duel, because she was sure that even with his grip broken she couldn't hold that chainsword back one-handed for more than a couple of seconds.
