Damage sharp cutting items

Cutting items have a sharp blade razors, knives, Cutlery and other). Under pressure blade cutting subject on the part of the body and simultaneously pulling formed incised wounds (Fig. 49). The features of these wounds are: form (straight, curved, zigzag)that depends on the direction of movement of a gun (or perpendicular angle), dehiscence of the Russian Academy of Sciences, the degree of which depends on the direction of dlinnie wounds in relation to the course of the fibers of the skin and elastic properties of it; smooth edges Russian Academy of Sciences, no sadnenia them; sharp ends of the RAS. If incised wound caused by a single movement, the wound has a typical linear form, if when removing guns from the wound, it turns and changes the direction of motion, there is an additional incision and the end of wounds takes the form of "dovetail"; considerable external bleeding, the severity of which depends on the calibre of the damaged vessels; lack of bruises in the surrounding tissues; the predominance of the length of the wound on its depth and width.

Profile wounds - a wedge-shaped, tapering into. On the walls and bottom of the wound can be detected by microscopic foreign particles (particles service, traces of metal, fragments of glass and others).
The bone injuries from sharp objects) limited surface notches.
Wounds from sharp objects, such as razors, neck and in areas with well-defined soft tissues can be very deep, in their turn can be damaged large vessels, such as the carotid artery. When such damage death can occur from either acute or heavy blood loss, or aspiration of blood, either from the air embolism through broken neck veins.
Localization cut wounds of different, its analysis is of great importance for forensic medical examination. To cut wounds inflicted by his own hand, are characterized by their location at the front of the neck, on the inner surfaces of the forearms. In the latter case, wounds quite often multiple, surface (sometimes one or two deep on the background of multiple surface), placed parallel to each other. At the end of wounds on the neck is often possible to identify a number of surface wounds-cuts, indicating the repeated movement of the cutting of the subject.

When the protection from attack cut wounds on the body of the victim (Fig. 50) can be localized on the Palmar surface or on the back of hands (covering parts of the body). Cause of death in these cases is often sharp or heavy blood loss, less often - shock, aspiration of blood, air embolism and other
