So I love this Kaywoodie I've just purchased. And I actually don't mind the stinger so much. A bit painful to pass a cleaner but no big deal. But look at thise pics. As far as I can tell, air only passes through the hole on the side, not on the end. I dont think the hole on the end goes through actually. Tried to run a needle so pretty sure it doesn't (or please correct me) my question is, why the holes on the end? Only thing I can think of is to catch a tobacco clog maybe? Anybody know?
