To track a large number of tools, the tools are kept in sets with each set having a container. A silhouette of each tool stored in the container is printed at the point of storage along with a data matrix symbology that has stored in binary code a description of the tool, the part number, and an identification of the kit of which it is a part. The associated tool has etched into the surface thereof a data matrix symbology containing the same information as the code printed at the point of storage. The data matrix symbology is readable by a scanner and a record of all the tools is maintained on a computer. Metal tools, may have a chrome, black oxide or stainless steel surface. To prepare the surface of a metal tool for receiving a data matrix symbology applied by a laser, the surface is sand blasted and coated with an suitable epoxy to inhance contrast.
