The pipe's bowl was carved of whale bone and elaborately decorated with ten miniature crab legs forming some kind of a crown. The shank and the mouthpiece were made of silver mined on the bottom of the ocean.
Jones filled the pipe with a mixture which burned under water which allowed him to smoke even when the Flying Dutchman was submerged.
Oddly enough, Jones didn't seem to smoke much while under the command of Lord Cutler Beckett, possibly due to his being up tight and under the East India Trading Company, giving him less time to casually ask "Do you fear death?".
