Hi ariel!
Yes, thats the feeling alright!
The Syrian or Lebanese one seems to be an old blade that is possibly rehilted. The Lohar I think is the best of the lot and in good condition, do you believe the story that came with it or do you think it's a "story" made to sell it? The Koummya I like because it seems to have a little quality to it. The split blade one is still a mystery to me as to it's origen even though the auction said Iran, when I get it maybe someone can read the inscription on the blade. I think it's blade is supposed to be like Zulfiqar the split sword of Mohammed or was it Ali( I forget who's it was).
P.S.- What does a lohar go for normally. How old do you think the jambiya is?
