It's laughably easy on hard (Chapter 4) with the knife.
You just need to run up to him and circle around him while staying really close ... he does absolutely nothing because the AI is not able to turn as fast as you circle. I highly doubt that it requires a certain skill to do this.
It also doesn't matter which side you choose, he's not able to keep up with you either way.
Though I hope that not a lot of people are still trying to play that ..... game.
