I must also add that the motifs and style of carvings on the hilt are not typically Mughal.  Closest I have seen are more related to Persian, but the quality of the carving again is not like that found in Persian ivory hilts (albeit a softer material). 
 
I must also agree with the possibility of dremel tool work looking at the micro-pictures.
