Recently I have acquired a very beautiful sword (maybe Qama?), but cannot find any information about it.
It is a large antique sword (length 25"), silver handle, silver sheath (21 ounces), silver decorations - tested - with a steel blade engraved and filled-in with gold phrases from Quran, sheath and handle decorated with cut out phrases in Arabic, bone (walrus ivory?) and mother of purl on the handle and sheath.
I will be happy with any information experts can provide. If someone could translate the engravings on the sheath and the blade - I would greatly appreciate it.
