I HATE owning things that I don't use. I'm sure we're all guilty of doing it, myself included, and more so than I would care to be the case. Lately I have been making a real effort to clear out my unused stuff. My wife and I took a truck load of stuff to the Goodwill last weekend, and it felt great.
I haven't bought a pipe in several years - the last pipe I bought was a Peterson 2018 Christmas pipe. I have a basic collection of "good smokers" that consists of run-of-the-mill factory pipes and a few cheapo basket pipes, and in truth I'm pretty happy with it. I have enough pipes to rotate, and I'm at a point where I don't want to add anything to my collection unless it's something I really want and intend to keep permanently.
Basically, I'd be interested in old British pipes and perhaps artisan pipes in more traditional shapes, yet I find myself never pulling the trigger on a pipe costing several hundred bucks, mainly just because there is this underlying feeling that my current collection gives me just about all the smoking enjoyment I could want. I'm sure I'll eventually open the flood gates and hopefully get something great enough that it makes me want to fill my collection with great pipes and let go of the average stuff.
