Are you a pipe smoker or a pipe collector? It may depend on your point of view. Let's see what G.L. Pease has to say about it in his May column for Pipes Magazine -
I was tempted to make a new thread for this ... but I've been spamming the forum a bit much lately. Oops.
How can you have only one pipe? Everything I've read is to let your pipe rest a day ... some advocate resting your pipe the amount of days equal to the amount of bowls smoked in the current day ... many others advocate using a different pipe for aromatics and non-aromatics (and some seem to go into even finer fidelity than that).
The only way I can imagine to smoke one pipe is if you smoke the same tobacco every single day and you don't care what it tastes like much. Is that a "pipe smoker"? ... well, sure, obviously it is technically. But in the sense of a "purist pipe smoker" vs a "collector"? Then I think not. In my personal opinion, to be a purist pipe smoker, one should actually care about the tobacco and what it tastes like and should also actually want to experiment and try smoking different tobaccos.
I don't want to insult anyone, but I can't help but think that if you only have one pipe you're simply a nicotine addict and a pipe is your preferred method of delivery. I suppose that still qualifies as a "pipe smoker", but maybe not in the context of what the OP intended ... I dunno ... just thinking out loud.
Annnyhooo ... to answer the question, I'd consider myself foremost a "pipe smoker" ... the pipe is the tool required for the job. However, to do the job well, one needs multiple pipes ... so .... both?
