AFTE Store - Toolmarks: Examining The Possibility of Subclass Characteristics

The identification of toolmarks to the tool working surface that produced them is dependent upon the significant reproducibility of individual characteristics. Subclass characteristics produced incidental to the manufacturing process can occur on several tool working surfaces. While some types of manufacturing processes impart individual characteristics exclusively, others may produce subclass characteristics on numerous tools. In this study, consecutively manufactured tools including pliers, cutters, punches, and chisels were examined for the presence of subclass characteristics and any possible effect on toolmarks produced by the tool. The manufacturing method used to produce the tool working surface is discussed as well as the effect of different manufacturing methods used to produce the same tool type.
