Foreshaft for a harpoon made from two pieces of ivory joined at an obliquely cut splice by five rivets. One of the rivets may be copper, and the others are iron. The narrowest end of the foreshaft, which would have been inserted into a socket at the base of a harpoon head, is cut straight across. The other end is rounded, which would have allowed it to swivel when inserted into a harpoon socket piece. This type of foreshaft is normally used for hunting seals at breathing holes.
