Hi Tim, I suppose this isn't the right place indeed. But the Piso Podang intrigued me so much. I cann't recall you showed this piece on the forum for comment.
From the pictures the blade seems laminated and the writing could be done on a local blade. Completely agree. But the tip under the magnify glass shows a different pattern. More pitting in contradiction to the laminated part.
But I thank you in the first place for the education in my own Dutch history

.
Herman Willem Daendels, it couldn't be more dutch, could be very likely the solution to this Piso Podang.
