Abstract: A high-strength fishing hook that includes a hook body, a hook eye fixedly connected to the top end of the hook body used for securing the hook, and a hook point at the other end of the hook body. Both sides of the hook body surface are stamped. The two stamped surfaces of the hook body are angled symmetrically to each other, forming a smaller hook thickness on outside edge of the hook body and gradually broadening up towards the inside edge of the hook.
