The only grain on a cob are the kernels.
If you look at the really old cob pipes they’ll have large areas where a kernel was. If you smoke one without resting those large pieces of cob get crumbly and flake off. Newer cob pipes use tighter grained cobs that had smaller kernels.

Missouri Meersschaum began commercial cobs but until 1975 or so they had lots of competition.
The first cobs were natural cobs with a reed stem. Now, they weren’t just any cob, but cobs that would not fit through a ring the factory provided farmers.
The companies advertised to farmers they’d get about ten dollars an acre for the cobs, if they’d plant a certain variety of corn. Back then corn was either hand picked and shucked or a mechanical corn picker was used. The cobs were good only as fuel or toilet paper, if there wasn’t a pipe factory around. $10 an acre was a BFD.
My family started planting hybrid corn early on my father said, using Funk’s.

The entire goal of the hybrid corn seed makers was to increase the yields of corn. Cobs were waste.
Why Missouri Meerschaum survived was they used a geneticist at the University of Missouri to develop a hybrid seed maximizing the size of the cobs and shrinking the size of kernels so their pipes would be tightly grained and larger. Since then MM contracts for cobs and the corn is the waste product, fed to livestock.
There is a fascinating museum at the Washington factory you can spend a day looking at the exhibits.
The Chinese make an inferior knock off of genuine MM pipes, but they cannot in any way compare to the real ones.

At one time MM and other makers fabricated the shank from cobs.
That’s the reason for the printed kernel pattern on the dowel rods they use today. I’ve noticed more pipes don’t have the cob pattern on the shank.
