May well be a screwdriver!
Certanly looks like one in that profile!
The only time Ive had such a tool with a kukri though it was as sharp as a carving chisel, so as most third tools with a kukri are for personel hygene, hair pullers,teeth cleaners,ear scoops etc. I cant realy say exactly what it is on just that photo.
Great observation Willem!
