This Mogul India or Persian silver inlaid dagger and matching sheath has a figural rams's head motif.
The dagger is covered overall with beautifully inlaid designs of leaves and interwoven line motifs in silver inlaid on iron/steel.
It dates to the Mogul Period in India or possibly Persia in the 18th-19th century. This is one piece from a small collection of Middle Eastern weapons (see last photo).
It is in outstanding condition with one small break in the silver inlay; possibly an old repair to the scabbard.
The blade has an unusual patterning on it, somewhat similar to the type of designs seen on Samurai swords caused by the constant folding of the steel upon itself when producing the blade. The blade may be old Damascus Steel.
