I have three Savenelli unfinished pipes, by which I mean, I bought them unfinished and they have slowly finished themselves as I have smoked them. The oldest, a zulu 404, I bought in the 1980's and it has developed a solid walnut color. My other two are a bent Dublin and a straight panel billiard/pot (rather short bowl). These all were sold as seconds in a basket pipe motif, but have few and inconspicuous fills. More recent advertised versions seem to be somewhat heavier; mine are all surprisingly light weight. I think smoking an unfinished pipe and watching it mellow into a superb natural finish is one of the most mellow of pipe smoking experiences. Anyone else experienced with these? Or other brands of unfinished pipes?
