Elite vintage tobacco pipe, smoking pipe, briar and horn

 (water buffalo or ox horn)  k1

Unsmoked from 1940s

 While briar is the perfect material for the bowl

 (heat resistance, non-toxic, beautiful grain),

 it's not ideal for the stem (the part you put in your mouth).

 Here’s why horn was historically used, 

and why it's still valued for the "connecting parts"

 of a vintage German pipe.

In short, the horn part serves three critical functions:

 durability, hygiene, and aesthetics.
