| Abstract: | The paper deals with the influence of the vertical angle of a tool on the resultant tool mark. Experiments were carried out using five screwdrivers on aluminium surfaces, the vertical angle of each screwdriver being varied from 90° to 25° in steps of 5°. It was found that differences in vertical angle greater than 15° may cause non-identity between two marks from the same tool. |
