[Korra's learned the hard way to be mindful of pressure points. Pressure points very close to where Hei is aiming are how the chi blockers took her bending (temporarily). That is something she finds far more threatening than the knife in his hands.
She can't block both at once, so she focuses on blocking the arm heading for her pressure point, ignoring the pain as his knife meets skin. In the next breath, she's grabbing for the wrist holding the knife. She heats up her hand, hot enough to burn, hopefully hot enough to get him to drop the knife.]
