Indian Arab Influenced Jambiya and Lots of Questions

[TVV]

Thank you Jens,
The mountings on the bhuj scabbard are very similar in style to those on my jambiya. However, while I can see the remnants of silvering on your example, the copper fittings on mine have definitely been gilded, not silvered. I am attaching some close-ups, which I hope illustrate this.
Why the artisan on mine chose to combine different materials in the hilt and scabbard I am not qure about, but Gene's explanation makes sense - perhaps copper was chosen as it was easier to pierce and rigidity was not required for those parts, which had the backing of the wooden scabbard.
Best regards,
Teodor
