With a little bit of cultural empathy one could imagine for which use an utility knife like four of the knives in question were used and for what. We speak about Congo knives, tropical climate! You have to make your own tools when you live rural, for nearly everything you need a knife, cutting plants you want to use and eat, animals you have hunted need to get skinned, later you need to cut the meat, in a rural kitchen there will be a knife always nearby.
Three other knives are clearly daggers, for what you need a dagger??
The other four ones, because they have the human shape, could also be ritual knives, when I look at the blades they were in long time use. Cutting the umbilical cord maybe? For the first hair cut?
There are numerous possibilities! But look simply at the patination of the wood, the condition of the blades before you tell another person who has paid good money plus shipping for them that these knives are tourist stuff and therefore worthless. Everybody who should be able to read patination will agree with me, that this is a very beautiful collection of minimum old Congolese ethnographic knives.
Sorry, when you felt attacked, this wasn't my aim. But after you have shown in another thread your very nice gile I was sure that you are able to read patination. And I really can not understand how someone can compare for example the both pictured handles and find them similar regarding quality, age, patination and so on.
