A chetnik dagger (kama), have the theory that this dagger was used by the komite in the balkan wars inspite of the 1941 that maybe came later, there is also an inscription Serbia Krushevac. Have been told that there were a komite school in Krushevac. If the man was a young boy in the balkanwars he may have been in WWII too or if the dagger were heritaged by another familymember. Because the handle is typically osmanian style and old. Beware there is a lot of fakes of chetnik daggers too. There is a very good maker in Serbia that makes "old" daggers. But this was bought in Austria.
