Use the quick rope (LT + Y + X) takedown on him ( easier if you do it right after jumping over him) and be quick with the quick time events especially near the end when he gets his blade out he will do 3 in a row everytime. Took me around 15-20 tries if you get hit reload the checkpoint don't give up it's a hard one
