Hello Manelo and thanks for your input,
I'll have to do a little research on the Canaries. I've seen the knife from there that resembles the plug bayonet, but never one with a guard or curved blade. Your logic of the trade routes does make sense, though.
Having looked through a million old catalogs of mine and perusing the web, I do see a more than slight resemblence with the so-called Fon war sword. Likewise, the curved short blades on some Nigerian pieces (still W Africa) could fit the bill, if not an exact fit. I still see more of a Spanish influence here with the European-style blade, D-guard hilt, strapwork grip and spiral quillon. The Spanish were in the Maghreb, but not in the Dahomey empire/area, more in Spanish Morocco. Likewise, we all know of the Spanish influence on Philippine weapons. As David succintly stated, this one might always remain in the mystery pile...
