Yeah, cobs have their uses. I have a number of them but they're not my favourites. I find them bumpkinish (which is why I never smoke them when wearing a suit); and they're also a pain to clean:Don’t get me wrong, I enjoy and appreciate my Savs. But they’re rarely the first pipe I reach for. As a simple smoking tool, the cob does the job (to coin a phrase).
PS: I feel the same way about used pipes.
That's the Morgan cob after several passes of the paper towel. With briars, the towel will come out white after 2-3 vigorous swabs, but with cobs the gunk is never ending: you evntually have to stop wiping, but if you wipe just one more time, you'll still get gunk on the paper towel. Frustrating. ?
They're not tough as nails either; unless you mean aluminium nails. That same Morgan eventually developed a crack along the shank. Beats me why: I don't abuse my cobs: I fondle them and clean them and preserve them just as any briar or Meerschaum.
Cobs are semi-disposable pipes: which is why I'm not getting bent out of shape over that Morgan breaking. it was never meant to last long.
