I think it's fake. I cut my finger and can't get it to stop bleeding for 5 minutes. He cuts off an arm and there's no blood. It looks like he's cutting a birthday cake. What little blood there is seems to be concentrated around the head, which is what you'd expect from somebody who has watched a lot of horror movies but didn't pay much attention in science class. For me, it's all in the details. If you did that to a human body, even if just from slitting the throat, that bed would be SOAKED in blood. Just an opinion.
