Where are tool impressions most likely to be found?

Tool impressions are most likely to be found on surfaces that are hard and can retain an indentation, making a car door a prime candidate. The metal surface of a car door is particularly suitable for capturing the unique characteristics of a tool that may have come into contact with it during a crime, such as burglary or vandalism. Tool marks and impressions can provide valuable forensic evidence by allowing investigators to match the impression to a specific tool, linking it to the suspect or the crime scene.

While tool impressions can theoretically be found on other items, their relatively soft nature or their lack of a suitable surface reduces the likelihood. For instance, a person's clothing is often too pliable and may not retain a clear impression, while the inside of a wallet typically doesn't present a solid surface where tool marks would be prominent. Lastly, a piece of paper lacks the hardness necessary to capture tool impressions effectively. Thus, the car door surfaces are the most conducive environment for capturing detailed tool impressions that can be useful in criminal investigations.
