Damage to the body caused by the action of sharp objects is one of the topical topics of forensic criminology. The variety of existing objects that can potentially be used for the purpose of committing a crime require a detailed traceological study. Purpose of the work: to carry out an analysis according to the study of the features of the morphology of heart stab-cut wounds, inflicted by national Uzbek knives. The material presented by 30 observations of those who died as a result of inflicting penetrating stab wounds with damage to the heart, inflicted by national Uzbek knives. Statistical processing of the obtained results was carried out using the MS Excel 2007 software. It was found that stab-cut wounds were more common in men, the wounds were mainly in the ventricles and less often in the atria. Stab-cut wounds inflicted by Uzbek national knives have an angular, oval, linear shape. The butt ends are П-, Г-, T-shaped, the blade ends are sharp. It was revealed that the walls of the heart, in comparison with skin wounds, have a higher morphological identification significance. The heart after restoration in Ratnevsky’s solution deformed less than skin wounds, and the length of the stab-cut wounds of the heart more accurately corresponds to the width of the blade of a stab-cut weapon. This may be due to the peculiarities of the structure of the epicardium and myocardium, which are less susceptible to the process of retraction. On the tissues of the heart, the design features of the butt and blade of knife blades are quite fully determined, so they can be used for group identification of a traumatic weapon.
