The prince, named after the Prince of Wales ( Prince Albert, later King Edward VII.) It first appeared in the 1920s and has a squat, rounded bowl with a long, usually very slightly bent stem and a short shank. Compared to the other pipes, the shank and the stem are thin and delicate, though not necessarily fragile. This makes for a light and comfortable pipe. It is normally made in three sizes (small, medium, large) and there exists a variant called the Cognac that is based on the shape of a brandy glass.
