Kindjal, filigreed sheath.

[rockelk]

New arrival, I have now in possession my shot in the dark. Only the blade is magnetic. There are light scratches on the back and I can see no copper underneath the scratch. I will have to get some dilute nitric to determine if it could be nickel silver. To me this is very nice filigree, but I would appreciate those with more experience to comment. Could this be black niello in the background with the silver polished? Has anyone seen a sheath done in this fashion? The blade has three fullers on the front and two on the back. I took a number of pictures. I hope I did not overdo it.
