Yes, called a Kai or Eku depending on who you ask. More for show / cultural, I'd rather have a stick. Define "learn" Not sure, I've seen a few advertised. Century might have one on it in there Panther stuff. I would have to disagree with you. Not for show. It is a very effective weapon. The small end is used to jab at the opponet, and the large end to hit. The large end was also used to fling dirt into the enemy's eyes. That move is actually used in most katas.
