Vintage Khyber Sword 16" Afghan Pakistani Punjabi Mexican? Replica? Dagger Knife For Sale

Vintage Khyber Sword 16" Afghan Pakistani Punjabi Mexican? Replica? Dagger KnifeI have never seen, nor can I find another knife exactly like this one. It looks like a cross between and Afghan Khyber and anOaxaca Mexico Dagger. I am unsure whether it is original or a replica but it is definitely old. it's in good condition for it's age. Needs to be cleaned up and sharpened. Edge has never been profiled, it's flat. There is a wiggle in the spine, not sure if it's from the forging or if it got bent and then bent back. See pics. Cool old piece. Needs some TLC. Sheath is rough.
