Self-harm (SH), also referred to as "self-injury" (SI), "self-inflicted violence" (SIV), "nonsuicidal self injury" (NSSI) or "self-injurious behaviour" (SIB), are different terms to ascribe behaviours where demonstrable injury is self-inflicted. The behaviour involves deliberate tissue damage that is usually performed without suicidal intent. The most common form of self-harm involves cutting of the skin using a sharp object, e. g. a knife or razor blade. The term "self-mutilation" is also sometimes used, although this phrase evokes connotations that some find worrisome, inaccurate, or offensive. "Self-inflicted wounds" is a specific term associated with soldiers to describe non-lethal injuries inflicted in order to obtain early dismissal from combat. This differs from the common definition of self-harm, as damage is inflicted for a specific secondary purpose. A broader definition of self-harm might also include those who inflict harm on their bodies by means of disordered eating.
