it does have a more pronounced 'S' curve than the more std. version like mine, and the knuckle guard is a nice touch. unsharpened ricasso is more of an indian style, but it still looks khyber to me. i like it. blade doesn't look like a turkish/balkan yat to me as it has the acute triangle look of the khyber knife. does it have a 'T' spine? can't tell from the photo.
my salawar yat for comparison
my balkan karakulak yat for comparison.
kinda reminds me of this one found googling:
found a notation somewhere that these style were also popular south of the khyber pashtun areas in india which may be the source of the atypical ricasso.
