Here is the actual top of the harpoon that i chose from the down town Anchorage Museum. It is the one to the left. Unfortunatly, only the tip of the harpoon is showing. From what I obsorbed, i could tell that the ivory head was dried out. As many people know, when the inner core of the ivory tusk dries out it tends to bend in the direction of the side where the majority of the sotfer center ivory is. For example, try raising your hand in front of you with your finger tips pointing up with your palm facing the right or left. Here is the concept, if the left side of your hand were to be the side with the inner core on it, it would curve in favor of that side. This is pronounced on this particular harpoon and is easily noticed when twirled around.
