Interesting sword. Charles posted a similar one not long ago here:

These swords appear to be a local interpretation of a Moroccan Saif in Western Africa, anywhere from Mauritania to Mali and Guinea. The leatherwork is reminiscent of the so called Mandingo swords. The hexagonal blade cross section is unusual, but can we tell for certain if this is a reworked Spanish blade or a locally made one? To me it looks like the latter.
