Excellent example of similar form. I also noticed in the pictures of the sword in question that in the 8th pic down from the top, there are line decorations near the throat of the blade. These look like an imitation of the tiered effect seen on so many bolos I've seen (you know, the ones people try to pass off as colonial American!
). The floral pattern on the knuckle bow...could it possibly suggest any particular area in the Philippines?
