Explanation:

An examination of a tool mark is essential when it comes to "Criminalistics" (the study of physical evidence in a crime). It allows the forensic investigator to know what kind of tool was used in the crime scene. There are only two kinds of characteristics of tool marks and these are: individual and class. Striated and molded are types of tool marks. They are not characteristics.

The "class" characteristic of a tool mark allows the investigator to know the shape of tool, its dimensions and its type. However, it doesn't point to the exact tool that was used, but it gives him an idea how the mark was actually created.
