Unknown dagger for ID and comment

[Araña_del_Sol]

Hi all,

This dagger (below) has defied my attempts to identify it. I suspect that it is African in origin but that is just a hunch, the blocky hilt with its rectangular cross-section is particularly unfamiliar to me. If anyone has insights on what it is or where it might be from, that would be greatly appreciated.

Overall length: 34.4 cm (~13.5 in.)
