Geez, how can people say that wrestling is fake and they don't hit each other with weapons. how do they get the sound effects then. does a camera guy go up to a fan and say "hey i don't like you" and hit the fan with a chair? NO! so the rumors are not true. wrestling is not fake, it is real
CASE CLOSED!!!  

Answer

I worked for a small independent promotion called Massillon Championship Wrestling in 2000 as a creative writer. Former WWE development talent BJ Payne, was our champion. The chair shots are indeed real. They nail each other with those chairs. You can see proof of this on the Beyond the Mat movie where you see Mick Foley getting stitches after his match with the Rock at the 1999 Royal Rumble. A lot of people don't realize how real wrestling is. Basically, the only fake thing about it is the outcome is pre determined.
Actually most of the punches never even touch the other person. And when they slam there head on to the steel steps they don't hit it with there head. They throw fake punches and fake kicks but the slams and stuff are real. Like wen Shane McMahon jumped off the entrance and tried to land on Kane but instead crashed through the floor, that cannot of been faked.

Answer

Depends on what the weapon is. With the steel chair, if the wrestler doesn't get his hands up in time to take the blow he gets nailed square in the head. When Triple H uses the sledge hammer, you will notice that he has his hand covering the end of the part that will impact with the wrestler. He 'pulls his punch', so to speak, so only a partial impact of the blow will be delivered to his opponent. With the trash can lids, they are aluminum. Very soft and practically bend in two after one delivery of the blow.
Fake is not a good word to use since it implies something that is 'not real'. The blows delivered with the weapons are very real. But they are meant to be pulled to lessen the impact or delivered with an object that makes a lot of noise but does very little damage.
