Help wanted for my Khanjar!

[chregu]

hello dom
Thank you for your answer.
Unfortunately, my English is so bad that it leads to misunderstandings!
I collect knives and daggers for 20 years!
I always assumed that the Ottoman, Persian and Indo-Persian curved daggers ar Khanjar or Kandshar, and the Arab curved daggers ar Jambiya.
more recently I know here in the forum, that only the Yemeni daggers be called Jambiya, all others Khanjar?
I still not understand the difference !
however, the difference between melting damask (wootz) and forged damask (damask steel) I know very well, because I know how to make it.

in the photo are almost all of my curved daggers shown.
for me so far: Khanjar top row, bottom row Jambiya
But the is not so?
I would like to learn more, but it is difficult, if man can not really English! sorry.
So please help me yet! when something is a Khanjar when Jambiya?
gruss chregu
