Claim 10:
11. A method of using a self-retrievable anchor, comprises:
submerging a self-retrievable anchor under water to a sea or a lake floor, wherein the self-retrievable anchor includes:
an interchangeable shovel; a hinge plate manifold removably attached to the interchangeable shovel, the hinge plate manifold defining a slot therebetween, and a first hole and a second hole perpendicular to the slot; a lever having a proximal and distal end, the proximal end defining a third hole and a fourth hole, and the distal end of the lever connected to a retrieving means; the lever disposed within the slot of the hinge plate manifold for the first and the second holes of the hinge plate manifold to align with the third and the fourth holes of the lever, respectively; a fuse pin disposed within the second and the fourth holes; and a pivot hinge pin disposed within the first and the third holes;
attempting to retrieve the self-retrievable anchor from the sea or lake floor;
applying tensional force on the retrieving means by pulling the retrieving means vertically from a boat;
increasing tensional force on the retrieving means, and breaking the fuse pin when ultimate tensile strength of the fuse pin is reached and ultimate tensile strength of the retrieving means is not reached;
rotating the interchangeable shovel in a 180° position after the fuse pin breaks relative to an original position of the interchangeable shovel before the fuse pin breaks; and
retrieving the self-retrievable anchor.
