Don't smoke it. l would never buy an old Kaywoodie for its smoking qualities. They were designed by salesmen for a mid 20th century public besotted by "scientific" gimmicks.I have a Kaywoodie that I inherited from my dad. For sentimental reasons, I don't want to get rid of it, but when I smoke it, it tends to gurgle. I don't have this problem with any other pipe. Any thoughts?
