West Sumba knife

[JeffS]

This Sumba chopper was a recent Ebay purchase. Nice patina on the handle and scabbard, seems to have some age. The figurines are fun, cool to see a nod to their horse culture and the clever use of handle and the kabeala scabbard style to create the interlocking horse and rider. Would the forging flaw on the blade visible in the photo below indicate layered construction? Also, I was surprised that the spine does not taper until it almost reaches the point. This is much more common in blades made by stock removal.
