A stab wound is an injury caused by a more or less sharp pointed
weapon when it is driven in through the skin and its depth is the
greatest dimension.
The size and shape of the stab wound in the skin is dependent on
the type of weapon, cutting surface, edge sharpness, width and
shape of weapon, body region stabbed, the angle of withdrawal, the
direction of thurst, the movement of blade in body, cleavage
direction, movement of person stabbed and the condition of tension
or relaxation of skin.
With a double-edged weapon the shape of the wound will be
elliptical or slit like and both angles will be sharp or pointed.
With a single-edged weapon, the shape will be triangular or wedge
shaped and one angle of the wound will be sharp, the other
rounded, blunt, or squared-off. Blunt end on the skin may have small
splits, so-called “fish-tailing” if the back edge of the blade is heavy.
A spear or another round object causes a circular wound.
