Thanks for that Nonoy.  It is very interesting.  From your picture the blade appears crudely made which is a surprise.  That does not mean in real space it is not well made.  It could be heavy, with good balanced and well shaped.  I was just expecting something very exciting judging from the most attractive scabbard.  It is more than likely that there is considerable varriation to the quality of shaping to these blades.  I have these two pieces the pictures are poor and the flash wipes away any subtlety.
