The Foursquare is a classic pipe shape, but it's most often rendered in straight configuration. Savinelli presents a bent version in the "513 KS" design. Like the traditional Foursquare, this piece offers the intriguing firmness of a paneled bowl and shank, but it angles the transition and turns the stem downward for a more balanced posture when clenched. Such a form retains the classic appeal of the pipe chart standard while subtly adding Savinelli's own creativity.
