The compound harpoon was the most prevalent weapon of the Aleut people. Also known as the toggle-head spear, it was about the same size as the simple harpoon and used to hunt the same animals, however, this harpoon provided a more efficient and lethal weapon. This harpoon separated into four parts. The longest part was the shaft with the thicker stalk closer to the tip of the harpoon. The shaft was fitted into the socket of the fore shaft and a bone ring was then placed over the joint to hold the two pieces together, as well as, protecting the wooden shaft from splitting. Connected to the fore shaft of the harpoon is the toggle head spear tip. This tip was made of two sub shafts that break apart on impact with an animal. The upper sub shaft held the razor stone head and attached to the lower sub shaft with a small braided twine loop. Once the tip penetrates the animal the upper sub head broke off from the rest of the shaft, however, since it was still connected with the braided loop it rotated the head into a horizontal position inside the animal's body so that it could not get away from the hunter.
