Cutting Edge-Complete the game only using a knife.
The trophy isn't shown popping due to the PS4 not recording it but you can see at the end that I am awarded the Cutting Edge Medal at the end of Barry's Campaign, I skipped all the cut scenes as well.
Also there is a issue with this trophy/achievement, it seems that the A.I. cannot shoot, throw a brick or even use crowbar. So please pay attention to your A.I. because yes they can mess up this trophy/achievement.
