Hello Jens,
no book, this is the picture from a well known italian auction house in Sarzana and the katar belongs to me now
. For a ridiculously low price.
I already polished the blade and the wootz pattern is incredibly fine and detailed. I have added a picture after the etching process before cleaning, you can see an arrow shaped hardening pattern at the tip of the blade, including the barbed hooks.
