Abstract: A collation feature permits rapid substitution of like size tool members between the families of tools by comparison of a common visual indicator assigned to commonly sized members of analogous tools having differing structural configuration. The visual indicia, advantageously disposed in a prominent position on the tool for unobstructed viewing, and includes at least one non-numerical identifying parameter, in the form of a color, combination of colors, and/or recognizable pattern. When a user of such tools discovers that he requires a different style wrench better suited to the application, he simply notes the pattern or color marked on the tool he is using and requests, for example, that his assistant hand him a differently configured tool designed for performing the same tool operation and carrying the same visually recognizable marking.
