Kaskara for Comment.

[Wodimi]

ahhhh....I forgot to show another Kaskara with an unusual Pommel. You can find it in AMNH and I think collected in 1914/15 in Egypt.
So maybe a Sudanese Kaskara was taken by Mamluk warriors of Ottoman Egypt and convert with such a handle in a Mameluke weapon. Only a thought.
There you also find this special headdress.
