Why does the stem cross the bottom of tobacco chamber on some Corncob pipes?

This is a feature of the Missouri meerschaum Co. products. A corncob pipe without wood on the bottom would break very soon. A cob of corn has no solid shape in cross section. There sits only corn starch. This would become damp by condensate or burn through quickly. Depending on the corncob model, a wooden plug is therefore installed on our corncobs. Alternatively or additionally (depending on the shape), the stem is pulled into the chamber. Another advantage: The opening of the stem is fairly vertical and at the lowest point of the chamber. A very positive feature that many Cob smokers appreciate is the positive result and side effect: The draft enters the chamber at the lowest point of the tobacco load. The stem in the chamber is intentionally built in and an important feature that distuingishes these pipes from other brands. Please note: These pipes have been made since the 1860s many hundred millions of times. Corncobs are iconic US products and iconic pipes with a rustic appearance and outstanding smoke properties. Please trust in this, if a corncobs for you at first may also appear unfamiliar and as a new kind of smoke pipe.
