The Trades that the Rodsmith’s Guild™ designates and defines are:

Designer:  An individual that designs/develops the taper(s), material composition, guide spacing, number of sections, ferrules, and any other design considerations or parameters used for the rod blank.  In essence, a Designer is the “architect” of the rod blank, but they may not be the individual fabricating the blank.

Maker:  An individual that fabricates the rod blank, regardless of what material is being used.  This individual may also (or may not) fabricate other components of the rod.  But an individual must fabricate the rod blank to be considered a Maker.

Builder:  An individual that assembles the various components into a completed rod.  A Builder may fabricate some, or all of the components used to complete the rod, but they do not fabricate the rod blank.
