    Abstract

    Tongue-and-groove pliers are often used in burglaries to twist off doorknobs (to gain entrance) and it was deemed necessary to determine if new, sequentially manufactured pliers would each produce similar toolmarks that would be indistinguishable. Evaluation of the toolmarks from three sets of sequentially broached Craftsman® pliers, together with an analysis of the manufacturing processes, verified that individual and not repetitive structural characteristics are generated.
