these do not appear to be re-profiled khybers, on close look, they're purpose made this way. the grips are different as well (and a bit smaller)
mine is much the same, tho i'm not gonna etch it to see if it's wootz thru all them engravings and inlays.
some of the earlier ones may not have had the raised edges these have, and may have been made as if they were small salawar yataghans, it's possible that a few were made from salvaged broken ones. how to tell tho?
