Srange all metal Indian WW2 knife?

[Freddy]

Tim, strange piece you found. The markings resemble a bit the ones on a takouba, don't you think ?

But here's a knife I found quite some time ago. I really don't know what to think of it. I found it on ebay and judging by the picture, I thought it was a Maasai dagger.

The handle is made out of leather rings. The knife blade has a strong middle rib. The bottom of the handle is fitted with a small bolt (???). This knife hasn't been sharpened yet.

Is it the work of an amateur trying out his knifemaking skills ?... But the shape of the blade is good. Perhaps a modern African knife ? Any suggestions ?

Total length : 28 cm. Lenght of blade : 17 cm. Handle : 10,2 cm.
