I recently purchased an M.M. Elf Cobbit and was planning on smoking through it last night. So I thought I'd give it a quick clean before lighting into it for the first time and noticed that inside the "shank" (I thinks that's what it's called), there was a fair amount of "saw dust" and splintering to the wood. I cleared the dust out and some of the splinters but even then, when I passed a pipe cleaner through it, it kinda shreds the fibers off the cleaner. Do I need to be concerned or should I just fire her up?
