A "J Type Chain Chase Hook" or "J Chain Chaser" is a specialized tool used to recover anchors and mooring lines from the seabed, particularly when the anchor has become embedded or the buoy and pennant have broken. It's designed with a J-shaped hook that can be used to grasp the anchor chain and pull the anchor out. The chaser material is not as hard as the chain and wire to minimize wear on the anchor chain.
