Hi Miguel,
Thank you very much, up to now you are the only one who tried to help.
I hope that you are joking about your jambiya! The first hadrami one is excellent!! It's a really good one. I'm more sceptical about the second one quiete recent. For the last one, difficult to say as it's an Indian jambiya and I know nothing about this kind, the shape looks good.
Unfortuntaly it's not what i was loooking for.
Kind regards,
Kubur
