Long time watcher of wrestling here...........They do actually cut themselves.............its called "bladeing"
They hide small pieces of razor blade in the tape they wrap the wrists, arms, etc with...........they get hit in the head with a chair or whatever, put their hands up, and cut themselves...........A small cut is all it takes as head wounds bleed a lot.
and just my .02................I can never condone what chris did. Horrible.................
And wrestling is NOT fake. It's scripted. There is a difference. Anyone who saw HHH's thigh muscle roll up his leg on tv cannot say that was fake, or watched Sid vicious break his leg. Let any of those guys pick you up over their head and slam you down on that mat and then tell me how fake it is. They do know the outcome before they ever "wrestle" but the moves and the hard knocks are real for sure...........A very grueling profession as you do it night after night.........200 days a year or so..............
What Benoit did was unforgivable though. What a shame.
