This is another hobby of mine I quite enjoy. But the thing I've noticed is, there are a god awful lot of pipe smoking snobs out there. These are the pipe smokers you need to avoid if you're just taking up this age old tradition. If you check blogs, YouTube, online magazines, etc., they always tend to favor the most expensive pipes and tobaccos. Pipe smoking is cheap. It's as expensive as you want to make it. When you start pipe smoking, you don't need to get an $90 pipe, $15 for 1 oz of tobacco, or pay $40 for a pipe tamper. That's insane. Here's what I enjoy, and prefer, personally.
1. Missouri Meerschaum Corn Cob Pipes: They're extremely affordable, are not porous, can hold a smoke for 30 minutes to 1 hour, depending on the size of the bowl, and can be easily replaced.
2. Clay Pipes: Even cheaper, are not porous, and have no cool down time. They are fragile, however, so be careful.
3. Blenders Gold or Sutliff Private Stock: Drugstore type tobaccos. They are extremely cool smokes, stay lit, and aren't very expensive. I also like Captain Black and Borkum Riff, but those are a bit expensive.
4. Pipe tool: These things range from free to $6, and include a reamer, poker, and tamper all-in-one.
5. Castleford Pipe Pouch: $6 on Amazon, and includes pipe tool and moisture pouch. The 4 pipe one is $30, but well worth the price.
Like any other hobby, it's as expensive as you want to make it.
