Hi Flavio,
Nice weapons grouping! and looks like you have the components for a great display. It is hard to describe the incredible feeling of satisfaction and pride that is issued by a well placed and tastefully themed display of weapons and associated items.
I think the Sudanese daggers could certainly be included in a display such as you are putting together, even with Somalian theme. The diffusion of these weapons with the tribal groups is of course well known, for instance, the kaskara though considered Sudanese, was known through Eritrea and obviously into Somalia. The familiar Hadendoa style daggers, also considered Sudanese are common in Danakil and Eritrea, often carried by Beja tribesmen into these areas.
As often has been said here, weapons have no geographic boundaries, and there are few limits to thier diffusion, whether through trade, warfare or nomadic movement.
Sure would like to see display when completed
