I don't smoke cigars so wouldn't know. My dad does, and I looked at cigars as an option just before I got into pipes but the cost put me off.[I was watching a video on YouTube recently where a cigar smoker reviews a thing called a Pigar. It's a pipe especially made for smoking cigars. ]
Jobpipe is a producer/vendor of pipes for cigars (you can google them).
I never tried a pipe dedicated for cigars as I am able to adapt the cigars to one or the other of the pipes (the key is getting a good seal of the cigar on the bowl). I can say a cigar in a pipe is definitely cooling the smoke which improves the taste and harshness at the end of the cigar.
