Please help on African piece

[fernando]

Thank you Freddy, your two blades are indeed cool .
But precisely as i mentioned, also in your examples the incized lines terminate together before the blade ends.
Thyst's why i thaught my blade was shortened, not because of the blade shape alone.
In the attached picture i try to transmit the idea, both in the incized pattern ending and in the space left in the scabbard, comparing to other example.
However i fully accept your observation that my blade was originaly like it is now.
In the next picture i am showing some pieces that i left behind, when i bought the Yaka sword. The guy would sell them cheap, but i found no interest at the m oment. Due to some browsing i have ben doing, i am now convinced that they are also Yaka. I call your attention for the one with the convex blade and the black shaft. Unlike the other two, this is not an arrow but a Yaka "scraping tool". I found that it is used to scrap some weed, but i don't know what is envolved in such operation.
Have you ever seen one of this, or know its actual scraping intention ?
Obviously you don't have to care about all this story at all .
All the best
Fernando
