Hi Lew, this has turned out more difficult than I had imagined.I have not found a knife labeled Leka only other southern forms with the rounded sides at the widest part of the blade.I shall have a look at the Leka northen neighbours.To illustrate my opinion is going to take a little time and a lot of use or scanner, camera, and editing, but talking African weapons is better than TV.In the meantime this map will show people where we are disscusing.
