Keyes' Pipe was a gift from his grandfather, likely a corncob pipe, used by the Captain to smoke tobacco. Despite being against regulations, Keyes kept it with him most times, using it to aid concentration - not necessarily by smoking it, but at least holding it. By the 26th Century, pipes like his had become antiquated, replaced by self-lighting cigars and cigarettes. Keyes smoked his pipe on the bridge once or twice when he was nervous, though it was against the regulations. He kept his pipe with him in his pocket.
