Also known as "Sand Pit", this feature is a concave depression in the Briar: a natural imperfection. Pits are found on all Briar, so even extraordinary Pipes may have a Pit or two. If the Pit is not too large, the Pipe maker may leave it exposed and not fill it in. Usually only extreme scrutiny will reveal these minor blemishes to the human eye, yet fastidious Pipe collectors are forever in search of the perfect, Pit-less Briar.
