Your Thoughts on this one

[archer]

Guessing this one may have turkish ribbon pattern?? It came highly polished and first etch displayed tempering at both blade tip and hilt. Both the horn hilt and scabbard show relieving for a normal raise ridged jambiya blade. Do you think the blade is as forged or was it reground removing the ridge and causing excess heat to the blade end? It's hard to photograph.
So is this another damaged blade case or what?

Steve, I do not think the pattern is Turkish Ribbon. It looks like sham: low contrast wootz, but I think it is mechanical, pattern weld and the low contrast was not caused by grinding - it was made/forged like this.

Alex, I also think that it's mechanically induced. It seemed weird that just the blade center was patterned and on either side there is a best just stripes of lamination showing. That why I asked if the center was a twist induced pattern.

Thank you,
Steve
