“ The edges and angles are not smooth and even enough for a stab-wound with a knife, for the edges are torn and not cut, and a stab-wound would be the only form of wound with which we would be likely to confuse it. Furthermore, the direction of the long axis of the wound parallel to that of the skin fibres in the region in which it occurs and the very slight retraction of the edges distinguish it from a stab-wound. By these signs we can almost always distinguish such wounds from stab-wounds, and thus tell the form of the weapon used. ”
