 AFAIK, neither Waldensians  nor  Genoese/Venetian  traders  ever reached Dahomey. IMHO, we are faced with a classical case of parallel development.
 Central European Kords ( Bauernwehrs) and Afghani  Khybers carry identical blades. Sardinian Leppas and Bedouin  Saifs have identical  handles.  Simple decorative elements such as circles  are  seen on Balkan and Afghani weapons. And so forth.
