The non-briar Kaywoodie may be Brylon, although I associate those mostly with Medico and Yello-Bole in later years when those brands tapered off on briar pipes, though their new briar pipes can still be found ... 4Noggins has some Medico briars for low prices. How Brylon pipes have hung on to the degree that they have is a mystery. One or two Forums members recommend Brylon for rough duty pipes. One man does fire reclamation work and likes the Brylon for being indestructible in that setting. Mostly, though, people find their bowls hot to the touch and not as kind to tobacco blends as briar, cob, Meerschaum, etc. Still, to stay in business, Brylon lines of pipes must have some repeat sales, so maybe the hard use sector has more action that we know. There may be guys or gals who have ten or twenty Brylon pipes who depend on them. None of them seem to be on Forums, or don't speak up. Brylon is a synthetic material containing some wood product, but other material as well. It was developed in the 1960's, I believe, not during World War II as a briar substitute as is sometimes told. Some Brylon pipes go for under $20, and most below $30. Some of the sales are likely attributable to new pipe smokers who want an inexpensive pipe but not a cob.
