Tim,
Why do you say your 'scorpion' is non-functional ? Perhaps because it has no sharp edgdes ? I once held one in my hands. It's quite heavy, no ? Perhaps it's just used as some kind of iron mace. Imagine what damage it would do if you used it to hit someone in the head.
By the way, let's start again. I'm sure Flavio also has something to show.
This is a classical Zande-throwing knife.
