It can also be a combination of those factors. I've seen at least 3 other Sulu kalis from the late 1800s-early 1900s era which also had shallow waves (and one of them was also twistcore). But admittedly, mine is the shallowest of them all

Ray, I think your example is more marked than many similar blades. Very shallow waves are a fairly common feature on some of the long, broad-bladed examples of the era you mentioned. I've seen them in Maguindanao and Maranao dress also.
