"Mayhem-- the intentional and wanton removal of a body part that would handicap a person's ability to defend himself in combat. Under the strict common law definition, initially this required damage to an eye or a limb, while cutting off an ear or a nose was deemed not sufficiently disabling. Later the meaning of the crime expanded to encompass any mutilation, disfigurement, or crippling act done using any instrument."--WiKi
