The intended usage of a tool is the basis for defining its features. The features of a tool determine its appropriate usage. Tools should perform reliably when used appropriately. A tool is sometimes applied to a task it was not intended for (e.g. a screwdriver applied as a chisel). In this instance, the performance of the tool may not be satisfactory due to an unrealistic expectation or failure of an implied capability. Recognizing unintended uses of a tool adds strength and character to it.

Not surprisingly, a small screwdriver is appropriate for turning small screws. This application assumes a set of criteria:

  • the width and thickness of the blade should accomodate a target set of screws.
  • the handle should provide a satisfactory human/tool interface within the constraints of comfort, torque capability and size.
  • the proportions should be suitable for the target operating environment.
Overall, the tools in this toolset are very suitable to their appropriate usage with some room for improvement in the tips of the interchanqeable screwdriver blades.
