Hi Ian,
I am interested to see that you have started a new love affair with African blades!
They have their own charm, don't they?
I can't be of great help but I see that three blades are daggers and all others seem to be utility knives.
Some of our Africa experts will give you an answer. But it's a beautiful grouping, they all together in a stand will be an eye catcher. Congrats, very nice catch!
Hope the shipping from Switzerland won't be too expensive, I have a very bad experience with an auction house from there.
Regards,
Detlef
