Thanks Tim. I used the word 'crude' not as a derogatory term, but rather as a way to descibe the forging of the blade I think there is a type of honesty in the fact that there is little or no machining in many examples of African weaponary. I have tried to forge a blade, and as you correctly state it is not as easy as it looks. I am sorry if you thought I was being insulting to the forger(s) of such weapons, but I am not.
Thankyou for the information, you have made my day.
