I think whether to buy pipes and less tobacco or the reverse is a question with which most pipesmokers struggle. Most decide to buy both . Well, maybe not. As has been said repeatedly, the tax man cometh. You can always buy pipes.
The lowly cob is really a prince. The universal image of the pipe is not a cob but a briar. I didn't even consider them for anything other than 1792 for a long time, and it was only after becoming dismayed by how much the briars I had bought that I gave them a far try. Now I really like smoking both and recently paid $116.00 for 10 Mark Twain models that have a chamber equivalent to a small group 4, the average size pipe. Cobs have regarded as throwaway pipes but the truth is that if handled with the appropriate care, they last, certainly not the for a lifetime like briar, but for years, surprising you with their resiliency.
So if tobacco is your choice, cobs are a natural choice for that duration.
