Spiral, please forgive my ignorance but other than the downcurved blade and a wooden grip held in place by 3 rivets, I fail to see the resemblance between my “thing” and these Guam knives. To me chamoro is basically a large bowie with a drooping blade. My choper is clearly leaf shaped and looks almost like a dowcurved barong or something. Plus, what leads you to believe that decorations on the blade are not swastikas and how do you explain a little hook-like protrusion on the ricasso? I am not trying to start an argument here as you are clearly an expert on this stuff. I am just trying to understand... Do you have any pictures of decorations attributed to Guam culture? I tried google but didn’t find much
