In modern North American pro wrestling, blading is almost exclusively performed by and on male performers; blading of women is extremely rare due to the risk of adverse publicity and the increasing use of female performers as "eye candy."
Typically, a wrestler will use a razor or other blade hidden in the tape covering his fingers or part of his hand(s) or somewhere else on his person. However, the wrestler always runs the risk of cutting too deeply and slicing an artery in the forehead. In 2004, Eddie Guerrero did this during Judgment Day 2004, resulting in blood loss severe enough to affect him for the next two weeks of shows.
Some wrestlers like Abdullah the Butcher, Dusty Rhodes, New Jack, and Devon Hughes (Brother Devon / D-Von Dudley) have massive, disfiguring scars on their heads from frequently blading throughout their careers. According to Mick Foley, the scars in Abdullah's forehead are so deep that he enjoys holding coins or gambling chips in them to entertain and/or scare people.
Today, blading is a lot less popular than in the past, due to the prevalence of AIDS and hepatitis. In the 1980s, the willingness to blade was seen as a benefit for new wrestlers.
Another such incident was during an ECW house show when a young wrestler known as Mass Transit forged documents and lied to ECW Owner/Promoter Paul Heyman about his age and amount of training. He then asked his opponent, New Jack, to blade him. Jack cut through two arteries in Mass Transit's head when he bladed the young man, and fifty stitches were required to close the wound. A wrestler allowing someone else to blade him is extremely rare.
