Perhaps the most iconic of all Peterson shapes, the "05" Calabash features a bowl flaring trumpet-like at the rim, a high transition to the shank, and a shank that is wide, muscular, and substantial in hand. Its wide base and smooth curvature, along with its easy-to-grasp, cinched waistline, have been prominent features admired by generations of smokers. Among Peterson's oldest and most popular shapes, the "05" epitomizes the Peterson design aesthetic.
