Radice saw it fit to load up this charming little bent Pot with several useful features that might make your smoke a little bit better. The twin bore system, while I cannot attest to the thermodynamic claims that it delivers a cooler, dryer smoke, I can agree that, because of indirect disbursement, unwanted "tongue-bit" can be partially alleviated. And because of the oil cured process, the break-in period is significantly reduced, if not eliminated altogether. The nasty sap, resins and moisture that the tenon is comprised of, and that naturally occur in the briar, have been extracted by the process. I cannot say that the "retro bark" design, a nod to the old Caminetto shapes, has any practical purpose though, beyond inciting nostalgia for the Bee Gees, Mork & Mindy, and custom vans, with shag carpet interior.
