Hi Emanuel,
the swords not mine....and the blade is curved. Thanks for the links.....one is in French so I've provided the link in English (below)

The buyer informed me that the blade was 2mm thick.....typically thin and flexible. It is quite likely you are right, that this should be called a Alguinjar. I cannot find any images to help confirm this.
