by the way, the book by Sercer, Marija. Jatagani u Povijesnom muzeju Hrvatske. Katalog muzejskih zbirki XI. Zagreb : Povijesni muzej Hrvatske, 1975.

is also partially available in German, made for an exhibition in Austria :

Jatagane aus dem Historischen Museum von Kroatien in Zagreb (Agram). Sonderausstellung im Landeszeughaus 9. April - 7. Juni 1976. Graz : Landeszeughaus am Landesmuseum Joanneum, 1976

with regards to " referring to the hilt as "bone," I think they mean horn," ; many hilts of yataghans, bichaqs and kamas were made also from bone ...the poor man's version or cheap repair of the ones and compared to the ones made from walrus, ivory or horn in the Balkans.

I have one yataghan which handle is not completly walrus or ivory, but had a repair from that time (19th century in which the of the handle, the "wing" wasthat badly damaged, that part got repaired / substitued locally by a piece of bone ; the epiphysis).
I shall try to make some good pics to show it.
