I must admit that many of the Ethiopian Euro bladed and hilted swords tend to be Cavalry Sabres with knucklebows...... The hilt (handle and pommel) does have a 'Kaskara' look about it.... with the addition of the Arabic script....
Wondering whether this could have been in the Sudan at some point in its life..... assuming the scabbard was the latest addition..... perhaps a 'captured' sword 'adopted' by an Ethiopian...

Bearing in mind the historical conflict between the two areas
Still a nice sword....with.....perhaps, many a tale to tell
