Need Help Finding blades

[CollectingNewbie]

Hi everyone, Im currently looking for a Turkish Yatagan and a Sinhalese Piha-Kaelta and any knives coming from Afghanistan. Im a poor college student so Im looking for maybe poorer (if thats even a word) quality blades, because sadily money is an issue. So if anyone knows where I could find any of these cheeper blades, or If anyones trying to get rid of their not so high quality items please let me know.
