Evidence can be grouped into categories involving the same color, size, model, brand, caliber, patterns, and other various descriptives. These items of evidence fall into groups of evidence having class characteristics, which display similarities but do not identify them as a match conclusively.
Items that match conclusively indicate that a certain item of evidence made impressions from normal wear or defects that make it unique. Only that item of evidence could have made those impressions or markings or only that item of evidence can be compared to another piece of evidence, showing that the two pieces were one. Those items of evidence have individual characteristics and to the exclusion of all others rule out any other similar item matching them.
