Sorry Radu, i wasn't trying to do any finger pointing. Of course i remember that you opened the thread. That's why i was wondering why you were trying to close it out so quickly. Generally that's what i assume when someone says,"...it's a closed chapter."
You are probably right, it might be a lot harder to sharpen a wavy blade evenly. But somehow the Moro know the trick because my wavy example is sharp as a razor all along it's length.
Perhaps testing could be done on materials that approximate the texture and hardness of flesh. Anyone have any ideas?
