Astabbing ispenetration or rough contact with a sharp or pointed object at close range.Stab connotes purposeful action, as by anassassin ormurderer, but it is also possible to accidentally stab oneself or others. Stabbing differs fromslashing orcutting in that the motion of the object used in a stabbing generally moves perpendicular to and directly into the victim's body, rather than being drawn across it.
Stab wounds is the specific form of penetrating trauma to the skin that results from stabbing.Stabbings have been common amonggangs and inprisons because knives are cheap, easy to acquire (or manufacture), easily concealable and relatively effective.Stabbing has also been usedin terrorism.
In 2013, about 8 million stabbings occurred worldwide.[1]
In the US in 2020, 9% of the 22,429homicides involved a sharp instrument; of these a larger proportion of females used a sharp instrument (13%) versus males (8.2%).[2]

Stabbings have been common throughout human history and were the means used toassassinate a number of distinguished historical figures, such as SecondCaliphUmar andRoman dictatorJulius Caesar andemperorCaligula.
In Japan, the historical practice of stabbing oneself deliberately inritual suicide is known asseppuku (more colloquiallyhara-kiri, literally "belly-cutting" since it involves cutting open the abdomen). The ritual is highly codified, and the person committing suicide is assisted by a "second" who is entrusted to decapitate him cleanly (and thus expedite death and prevent an undignified spectacle) once he has made the abdominal wound.
The humanskin has a somewhat elastic property as a self-defense; when the human body is stabbed by a thin object such as a smallkitchen knife, the skin often closes tightly around the object and closes again if the object is removed, which can trap some blood within the body. It has thus been speculated that thefuller, an elongated concave depression in a metal blade, functions to let blood out of the body in order to cause more damage. This misconception has led to fullers becoming widely known as "blood grooves". The fuller is actually a structural reinforcement of the blade similar in design to a metal I-beam used in construction. However,internal bleeding is just as dangerous as external bleeding; if enough blood vessels are severed to cause serious injury, the skin's elasticity will do nothing to prevent blood from exiting the circulatory system and accumulating uselessly in other parts of the body.
Death from stabbing is caused byshock, severeblood loss, infection, or loss of function of an essential organ such as theheart and/orlungs.
Although previously a victim of abdominal stabbing would be subject to exploratory surgerylaparotomy, it is now considered safe not to operate if the patient is stable. In that case, they should be observed for signs of decompensation indicating a serious injury. If the patient initially presents stabbing injuries and is unstable, then laparotomy should be initiated to discover and rectify any internal injury.
When someone who has sustained a stab wound dies, the body is autopsied and the wound is inspected by aforensic pathologist. Such examination can yield valuable information about the weapon used to produce the injury. From the external appearance and internal findings, the pathologist will usually be able to offer opinion about the dimensions of the weapon including the width and minimum possible length of the blade. It is possible to determine whether the weapon was single edged or double edged.[3]
Sometimes factors like the taper of the blade and movement of knife in the wound can also be determined.Bruises orabrasions may give information about theguard.[3]
