[The histological study of puncture-stab wounds of the skin for establishing the characteristics of the design of the knife blade].
Histologic studies can help disclose the design of the knife blade by which a cut wound was inflicted. For analysis, thick (25-30 microns) sections are made, parallel to skin surface near the ends of a cut wound. The ends of the wound formed by the blade edge and back are different, and some specific features of the blade back, primarily its thickness, can be distinguished. When the suspected knife is available, a valid conclusion can be made by comparing experimental wounds inflicted by this knife with the studied wounds.
