Cut steel decorations on Indian arms

[kronckew]

My katar has a blade carrier section with a rapier blade tip inserted and riveted. the carrier section was tabbed and inserted into corresponding square holes in the curved crossbar, they appear to have either been shrink fitted and peened or forge welded together. Very hard to see as it has cut steel decorations and cross hatching, but there appear to be 5 tabs you can make out, less noticeable in the photos tho.
