Dear All,
Here is a fantastic book on khevsurian fencing (in russian). It also shows some rare pictures of khevsurian equipment.

There are three things I would add:
a. The reader of djvu format is available at

b. In the text khevsurian swords are wrongly identified as of western manufacture, they were made locally. However, mail was mostly made in Kubachi.
c. The book mostly talks about ritualistic, non-combat fencing.
