Hardcore wrestling is a form of professional wrestling where disqualifications, count-outs, and all other different rules do not apply. Taking place in usual or unusual environments, hardcore wrestling matches allow the use of numerous items, including ladders, tables, chairs, thumbtacks, barbed wire, light tubes, shovels, glass, baseball bats and other improvised weapons used as foreign objects. Although hardcore wrestling is a staple of most wrestling promotions, where they are often used at the climaxes of feuds, some promotions specialize in hardcore wrestling, with many matches performed in this manner.
