Traditional scripts are written with a metal nib in a holder (oblique or straight) and dipped in ink.  There are hundreds of different types of nibs but to keep it simple, the dip pen uses a pointed nib or a broad edge nib.  The traditional scripts like Copperplate, Italic and Textualis Quadrata follow very specific rules.  Various types of ink can be used from Sumi ink, Gouche to watercolour paint.
