Yehh it is common knowledge that wrestler's blade themselves.
It is alwyas obvious when they do it too. Msot times, if a wrestler is outside the ring, they will roll towards the ring apron and the camera will cut away from them, then whilst the camera is off them, they will blade themselves (usually with a blade which is concealed within their taped wrist). Then when the camera is back on them, they look like they have been cut to hell. Prime example: Shawn Michaels.
