There is a type of hand tool that is specifically made for cutting profiles into the curved end grain of (for example) a pembroke table. One word for it is a "coachmaker's shave", another one is a "sash shave". This is a link to a picture of one on Lee Richmond's The Best Things site:

These types of tools will generally only work well on gentle curves, and one generally has a pair, one right-handed and one left-handed so that you can work "downhill" on the endgrain. American examples are sometimes "double ended" in that both directions are made into one tool.
For the gooseneck moldings that one typically sees on queen anne and chippendale colonial furniture, they were produced almost exclusively with carving tools, as Al notes. Period examples sometimes show evidence of being scraped with a profiled scraper after carving, others still bear small facets left by the carving tools.
