Subclass Characteristics Workshop

This three-day (24 hour) workshop explores the historical development and evolution of  “Subclass Characteristics” and critically examines the use and definition of the term. A wide variety of firearm and tool manufacturing processes commonly encountered in the industry will be evaluated for subclass potential. Methods of recognizing potential subclass characteristics on tooled surfaces will be examined. Lab practices, interpretation, and legal challenges will be discussed. Emphasis will be on recognizing or eliminating the potential of subclass involvement, developing strategies to ensure identifications are not subclass in nature, and exploring documentation and report writing methods when subclass influence is suspected.

This class combines lecture with heavy emphasis on laboratory/microscopic time, focusing on the examination of toolmarks made from numerous consecutively manufactured tools.

Comparison microscopes and projector/screen for PPT. No more than 1 to 3 students per comparison microscope suggested.
