[Defined contusion marks caused by the knife handle].
If in inflicting a stab wound the knife is vigorously pushed in up to the end of the blade, this does not only cause cutting of the tissue, but also a blunt traumatization. The resulting abrasions can correspond with the respective construction parts (handle, handguard, devices for fixing the open blade) as to position, shape and size, thus allowing conclusions as to the shape of the instrument used. Incomplete, one-sided marks of the handle suggest an oblique-angled stab. The presence of a contusion mark shows that the blade penetrated completely, which makes it easier to draw conclusions as to the length of the blade from the depth of penetration. The reconstruction possibilities are demonstrated on the basis of three autopsies (homicide cases with different types of knives).
