Comment：Bone and antler implements from the Okhotsk culture are rich in their quality and quantity. The harpoon head, which is part of a harpoon, is a representative example, and it comes in many forms. The samples in the figure were hafted, and an arrowhead was attached to the first three and the seventh samples (counting from the left). All of them were used for hunting sea mammals or large fish.
