Mechanically Spread Barbs Patents (Class 294/127)
  • Patent number: 8677675
    Abstract: The multi-pronged spear-fishing spear tip includes a collar for mounting the multi-pronged spear-fishing spear tip onto a spear shaft. An elongate center tine extends axially from the collar and includes a spear point for piercing fish or prey. A plurality of diverging tines with piercing tips surround the center tine, the diverging tines immobilizing the fish or prey pierced by the center tine. Each diverging tine extends from the collar at a diverging angle from the axis of the collar. The length of the center tine is longer than the length of the diverging tines to accommodate most sizes of fish or prey. This construction provides the functionality of a single-point spear and a paralyzer spear in a single unit.

  • Patent number: 4024665
    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.
