The shape is important because it tells us that the bow was of composite construction. It also gives an indication of the origin of the bow, because angular bows were associated with western Asia.
In inscription H-682, the angular bow is used to refer to a geographical area. Unfortunately, it is not possible to say what that geographical area was.
