Kool-Smok: It was a pipe based off the Viking and Falcon designs. It is an aluminum pipe with a briar screw in bowl, that has a nut at the base of the bowl that can be adjusted to increase or decrease airflow, and with cooling fins on the stem that are cut at an angle and from the side give the impression of a corkscrew (see example).
