This was in the small lot of ulu knives that I was able to recently purchase. The entire knife is made from a single piece of metal. Cut and rolled to form the handle. Given the scarcity of metal in the area, I am assuming that this one is newer than the others in the lot, but seeing the corrosion, I believe it still has at least a little age on it. Because the tips of the blade are not swept out at all has me questioning if this is truly an ulu, or a tenderfoot's interpretation and intended for use as a vegetable chopper.
