Claim 17:
18. A self-retrievable anchor, comprising:
an interchangeable shovel, a lever, and a hinge plate manifold that contains no welds therebetween for eliminating welding failure when a weld is subjected to tensional and bending forces during anchor retrieval;
the lever attached to a retrieving means and the lever disposed within the manifold, and the manifold removably attached to the interchangeable shovel;
the lever further attached to the manifold by at least a fuse pin that has a specific dimension depending on an anchor size so that when a tensional force is applied by the retrieving means above fuse pin shear strength capacity, and below breaking strength of the retrieving means, the fuse pin breaks forcing the interchangeable shovel to rotate 180° from an original position of the interchangeable shovel; and
wherein the self-retrievable anchor is released when stuck at a sea or a lake floor bottom.
