Significance of Beaded Edges/Borders on South Indian Weapons?

[ariel]

If you really want to go into architectural details, Google " crenellated wall india" ( couple of examples below)

Just pay attention: some images in this series are from Italy, West Africa, Jerusalem, France, Poland etc etc. Crenellation is one of the most popular architectural designs, originally intended for purely military purposes ( see three last images with very early European castle wall, predating Indian fancier examples ), but later becoming a decoration.

Personally, I doubt there is any symbolic or sacral connection between different crenellations ( architecture on the one hand vs. jewelry, weapons etc.).

And, re. your assertion that Mughal architecture should not be counted, the upper right image, with the prettiest onion-like crenellations, the closest to the decorative ones on the handles and jewelry, is a part of Taj Mahal, the ultimate Mughal architectural monument.
