Blading has been common in wrestling for about 80 years. fake blood will be used it backstage taped parts of the show where it can be applied without anyone noticing, in front of a crowd it's none with a razor blade, usually within the hairline or the top of the forehead where the scars won't be so noticeable. Of course, there are exceptions, see Steve Corino. Lots of blood capsules in that mans past.
