The Three Major Kind of Tools

* Tools for hitting things to make them loose or to tighten them up or
  jar their many complex, sophisticated electrical parts in such a
  manner that they function perfectly.  (These are your hammers, maces,
  bludgeons, and truncheons.)

* Tools that, if dropped properly, can penetrate your foot.  (Awls)

* Tools that nobody should ever use because the potential danger is far
  greater than the value of any project that could possibly result.
  (Power saws, power drills, power staplers, any kind of tool that uses
  any kind of power more advanced than flashlight batteries.)
