The "673 KS" shape is Savinelli's take on the iconic bent Bulldog design. While the overall profile remains true to the traditional English shape-chart standard — marked by a paneled shank and tapered rim — the Italian marque has imbued it with their own stylized aesthetic. Most notably, the shank is triangular instead of diamond in cross section, a signature Savinelli shaping cue, and the bowl features some added plumpness about the base before tapering slightly toward the rim above the waist. It makes for a distinctly recognizable Savinelli pipe, replete with a substantial voluptuousness in hand, while still maintaining a strong degree of classic appeal.

Like the Arlecchino and Gianduia lines, Savinelli's Colombina series celebrates the commedia dell'arte and honors Colombina, a comedic wife character in Italian theater. Available only in the marque's "673" Bulldog, the series centers around a red and blue stem whose hues evoke the look of Colombina's colorful costume. This series is offered in either a light smooth finish or a craggy rustication, with the latter presented here.
