It seems the two of them were both testing the waters here, checking eachother's strengths and weaknesses. I say that because of the fist headed towards Kanitah's face. Now, if he had the drive to, he would have decided upon the more 'cool' choice of headbutting Fury's hand. However, knowing that his foe is more than capable of moving his body with a punch, he decided to reciprocate the action. Turning his head and tilting his neck to the left the punch ran across his beard in a harmless way.

Pushing himself forward up Fury's arm he spun around and raised his left arm, bringing it upwards over Fury's own and riding with it. Taking two steps forward, Kanitah's intention was clear. With his weight behind it he was going to strike Fury with the flat of his arm, making his two forearm rings strike him in the face. 

Unaware of Fury's ability to consume energy, he was not aware of the chance to have those rings actually feed his foe. However, in his experience with fighting those who take the lives of others so lightly. The rings that Darligrov supplies him with were never pleasant to feel rubbing across one's face. Most certainly not when it's been swung forwards like a warhammer in motion.
