Hi Tim, 
 
Welcome to the forum and thank you for sharing a nice wootz bladed katar.  The wootz pattern is very nice and looks nice and consistent throughout.  Dating katars can be difficult because stylistically they cover a long period of time.  My gut on this one from the picture is probably early to mid 19th century.  Specific regional attribution can be difficult and I don't see any distinguishing features in this example to help me with that but perhaps someone else can.
