Possibility of defining one-blade knife width by chest wound skin scraps sent for laboratory investigation is presented in the article. The research was done in 1984–2002. Only those cases were considered when there was no doubt that the wounds had been inflicted by concrete knives. The perished were 52 people (40 men and 12 women). The problem was solved how to determine the primary length of wound main part (that is what length the wound was before cutting it out from the corpse). To define it asking scrap was soaked in a spirit – acetic acid liquid (the first A. N. Ratnevsky solution). The length of the main part of a wound was measured by means of stereomicroscope MBS–9. The wound primary length was calculated using the following formula: 0,84 0,06sin l L (1) Where L – a sought for wound primary length, l – the length of the wound in the skin scrap restoring its primary form (after soaking), – the angle between the wound lengthwise axis and Langer lines course. This formula was suggested by the cancer registry head of Lithuania, Dr. Juozas Kurtinaitis (Vilnius University Cancer Institute since 2003). P. P. Komarov has solved that chest wound cuts per every edge width centimeter were short of 0,64–0,82 mm. To our mind, one can define the knife-edge width by the wound length and base on the before–mentioned skin wound length and knife blade width dependence. The average indicated parameter size 0,73 mm was chosen. Therefore the knife-blade width was defined by the formula: Fe L1,073mm (2) Where Fe – the knife-blade width in millimeters, L – the length of the wound defined by the first formula.
