Rob and Ki you may both be right...
Following up on Ki's information regarding geographic origin. This from the site:
http://www.le-betel.com/betel/ciseau...9/en_ci009.htm
"Betel cutter of the « Katar » style. One of India’s most characteristic edged weapons. It has a triangular bladed punch-dagger. This cutter is very much like the « Katar », when turned upside down it is a weapon, and otherwise merely a silver betel cutter without any decoration. This betel cutter is used by women to protect themselves."

Very interesting. Thanks for all the help.
Have to trot a few of my other mysteries in coming weeks.
