Hi All,
Currently, there are some droolingly gorgeous African weapons coming out of hiding.  Since I didn't know much about them before (aside from that "swords" picture in Stone's 
Glossary), I'm finding this fascinating.
I'm going to pitch a question to the list: why are the Central African swords and knives so diverse in shape, and so frequently of marginal functionality? 
Here's my guess: basically, the swords were generally side-arms, with something else, such as a spear or bow, being the main arm.  Flavio's picture of the armed tribesman on Louie's Kuba thread is a case in point.  As side arms, the swords and knives primarily play a symbolic role, and their use as weapons is secondary.  In this way, they're more like a keris than like, say, a European sword.  
What do all you experts think?  Feel free to post more pics too, while you're at it! 
 
Cheers,
Fearn
