One of Savinelli's signature shapes, the 173 is a novel hybrid of Apple and Bulldog designs, featuring the more rounded bowl of the former with a domed, triangular shank. Here in the Tortuga series, it's finished in a dark rustication with a tortoise-patterned acrylic stem, as well as a matching removable rim cap that allows customers to pause during a bowl and save it for later without fear of spilling ash.
