Well, while searching for similar sheaths to make some comparisons, I did found something very interesting, namely the first picture below. Sadly, I wasn't able to find its source or anymore information about it besides the file name ("mandingo short sword old african dagger antique knife"), but I think this is still a very interesting find for several reasons.
First, and even without seeing the blade, it is a way closer match to my knife than any faca de ponta I've seen before : the handle is very similar in shape, seems to be entirely made out of bronze/brass, and with the same central turned, dark wood insert ; at first I even thought it was an old picture of my knife before noticing some slight differences. Second very interesting point : the sheath, which is also in a very distinctive african fashion, similar to what can be seen on some Mandingo/Malian knives.
It's not much, but it is definitely adding weight to Tim Simmons theory, and I would love if he could tell me more about it.
Kronckew :
This lot was sold by a private seller, not a dealer, and considering the comparable state of all of the knives, I'm led to believe that the lot wasn't created yesterday, but I might be wrong. Regarding the sheath, I don't think the loops were added later : the leather is similar to what was used on the rest of the sheath and shows similar wear, it is also a very common fastening method on african knives (see examples below) ; also, the embroidered motives made out of thin leather strips reminds me of what can be found on some Mandingo knives sheaths.
Detlef :
I also have a picture with the knives out of their sheaths, but I don't think the knife to the right of mine is a faca de ponta.
Anyway, thanks a lot to all of you for your help and suggestions, this is very interesting !
