, 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 the fuller, 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,

, 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.

. 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. Sometimes factors like the taper of the blade and movement of knife in the wound can also be determined.
