My wife and I are sitting outside and I just finished a bowl of McClelland Yenidje Supreme. As I was cleaning the pipe out my wife asked my how long the pipe should last if I smoked one bowl a day in it. I thought about it for a minute, said I didn't really know, but that I thought the pipe should certainly outlast me and if cared for could last almost indefinitely.... I did add that the stem might have to replaced from time to time depended on chewing/clenching. Any thoughts?
