Hi, DanielUka,
My name is also Daniel
The sword from the first picture is a Balkan yataghan, which grip is revamped late, it is not the original one. Such swords you may find in Bulgaria-revamped or with grips/handles made in a hurry as people had to be supplied with swords very quickly during the Bulgarian April Uprising in 1876. I am not sure where this swords originates from, but it was made/revamped in the same way.
As far as the second picture is concerned - it is a typical karakulak, as the missing grip of the sword was made by a buffalo horn.
Here I send pictures of my collection of karakulas, so if you decide you may recover the missing grips/handles.
Best regards,
Dandi
