<p class="MsoNormal" style="margin-bottom: .0001pt; text-align: justify; line-height: normal;"><span style="font-size: 12.0pt; font-family: 'Arial','sans-serif'; mso-fareast-font-family: 'Times New Roman'; color: black; mso-fareast-language: EN-IN; mso-bidi-language: HI;">A forensic science that is used in identifying the owner of the tool by linking the tool mark to a crime is referred to as toolmark analysis. Whether one is investigating a burglary, a violent crime or some other complicated case of sabotage, toolmark analysis offers solid evidence for solving the case. In this blog, we will be defining toolmark analysis, exploring how it is used and why tools are vital tools in the modern forensic world.</span></p><h1><span style="mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-IN; mso-bidi-language: HI;">What is Tool Mark Analysis?</span></h1><p class="MsoNormal" style="margin-bottom: .0001pt; text-align: justify; line-height: normal;"><span style="font-size: 12.0pt; font-family: 'Arial','sans-serif'; mso-fareast-font-family: 'Times New Roman'; color: black; mso-fareast-language: EN-IN; mso-bidi-language: HI;">Toolmark comparison entails the inspection of impressions that were made by a tool on a surface inclusive of metal, wood and plastic. Such marks are known as toolmarks and are distinct from the tool that produced such marks through wears, damages as well as imperfections when manufactured. Through comparison with suspect tools, the forensic specialist is able to provide a straightforward link between a tool and a scene.</span></p><h2><span style="mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-IN; mso-bidi-language: HI;">Types of Tool Marks</span></h2><h3><span style="mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-IN; mso-bidi-language: HI;">1. Impressed Toolmarks</span></h3><p class="MsoNormal" style="margin-bottom: .0001pt; text-align: justify; line-height: normal;"><span style="font-size: 12.0pt; font-family: 'Arial','sans-serif'; mso-fareast-font-family: 'Times New Roman'; color: black; mso-fareast-language: EN-IN; mso-bidi-language: HI;">These are made when a tool rubs against a surface without translation. For instance the impression when one uses a hammer to strike a door.</span></p><h3><span style="mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-IN; mso-bidi-language: HI;">2. Striated Toolmarks</span></h3><p class="MsoNormal" style="margin-bottom: .0001pt; text-align: justify; line-height: normal;"><span style="font-size: 12.0pt; font-family: 'Arial','sans-serif'; mso-fareast-font-family: 'Times New Roman'; color: black; mso-fareast-language: EN-IN; mso-bidi-language: HI;">Frictional marks arise when two surfaces are rubbed together using a tool such as a screwdriver cutting a lock on the door.</span></p><h4><span style="mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-IN; mso-bidi-language: HI;">3. Combination Marks</span></h4><p class="MsoNormal" style="margin-bottom: .0001pt; text-align: justify; line-height: normal;"><span style="font-size: 12.0pt; font-family: 'Arial','sans-serif'; mso-fareast-font-family: 'Times New Roman'; color: black; mso-fareast-language: EN-IN; mso-bidi-language: HI;">Some toolmarks are a mixture of impressed and striated characteristics more frequently observed in complicated scenes.</span></p><h2><span style="mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-IN; mso-bidi-language: HI;">The Use of Toolmark Analysis</span></h2><h3><span style="mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-IN; mso-bidi-language: HI;">1.
