Abstract
The fish spear includes a shaft with scissor-like blades on one end, the front edges of the blades defining barbs and the back edges being smooth. When the blades are in closed position, a spear shape is defined for spearing a fish. When the blades open past each other, the front edges with the barbs penetrate the flesh of the fish and retain the fish on the spear. A manually operable pull cable connected to the blades will move them to their closed position, thus retracting the barbs and permitting easy removal of the spear from the fish.
