I’m still fairly new to pipe smoking myself, but I would say as long as you take care of your pipes properly they should out last me or you. I would also say that yeah, a longer pipe such as a Churchwarden would give a cooler smoke versus say a nose warmer. The main way, in my limited expensive, to control the temperature of your smoke from a pipe would be how often and how hard you puff on it. I’m sure more experienced pipers will chime in with better knowledge than me.so I have a few questions, I know to start with a cob but do pipe get worn out? Also how much does the shape of the pipe make in the smoke like a longer pipe give cooler smoke then a shorter pipe?
Yes, I've heard and seen some cob pipes get "burnt out" but some proper care and maintenance should last you a lifetime with care. I've read some beeswax helps coat the outside of a cob bowl too. But, like Jody said too, I think it's more so how "hard" you puff on the pipe to make the pipe hot or cold. Some tobaccos will burn hotter or cooler than others plus the way your bowl is packed and temperature in the area you're smoking etc. The shape of the pipe I don't think matters at all.so I have a few questions, I know to start with a cob but do pipe get worn out?
