Hand Tools, Sewing  Machines, and the  Parachute Loft Chapter 6 Introduction Riggers are taught that there are three things necessary to do  a proper job: knowledge to do the work, the correct materials,  and the right tools. The job cannot be done correctly without  all three of these essentials. The right tools include various  types of sewing machines, as well as a wide variety of  specialized hand tools. The importance of learning the names and nomenclature  of rigging tools and equipment cannot be overemphasized.  Just as learning the language of a foreign country allows an  individual to live and operate efficiently within a society,  learning the language of the rigger allows new riggers to  operate and interact within their profession. Without the  necessary vocabulary, a rigger is not able to work with other  riggers and, more importantly, does not present a professional  image to customers. For example, when shopping for tools  or sewing machines for rigging, the same tool may have a  different name when used by some other trade. Knowing the  language of the rigger helps avoid confusion.
