Always fun to have a modern knife turn up with possible clues as to from where it came. You headed up the post as Indian? Is that a clue or where in fact did you get it?...The pattern on the blade is reflected in the hilt for which I think its origin points at
tree of life which could be the vast area of India and or the Silk Road not to mention Arabia or Muslim origins broadly. I will hazard a vast guess ...Afghanistan! I would say Kabul.
