20080263931 | Rabbit ear no-gaff spear - The present invention includes a spear tip that is removably mounted onto the upper end of a spear shaft, which is securely engaged upon the upper end of a handle. A rubber band secures the spear tip to the upper end of the spear shaft. Spear tip has a conical portion integrally formed upon the top of a cylindrical portion. A cable is fixed to the spear point by passing the end of cable through a transverse passageway formed through the cylindrical portion below conical portion and forming a loop at the end of the cable. A pair of parallel rabbit ears is affixed to opposing sides of the cylindrical portion. The cable is adapted with a quick connect/disconnect mechanism. | 10-30-2008 |
20080263932 | Swivel point fish gig - A simple efficient novel design fishing spear assembly for sport fishing includes a spear point pivotally mounted to the upper end of a spear shaft. The spear point swivels from 0 degrees to 180 degrees. The spear point and shaft is mounted onto a long handle to support under water spear fishing, wade fishing, spear fishing or gig fishing from vessel. The ranges of rotation support the spear point between an insertion position, a retaining position, and a withdrawal position. A ball cooperatively engaging with a locking mechanism secures the spear point within the desired position. The long handle can range from a few feet to several feet depending on the application or need. | 10-30-2008 |
20090100738 | FISH HARVESTING HEAD - A fish harvesting head with a rotatable barb device that is held in place with a piercing tip and is configured to move between fish piercing, fish retaining and fish releasing positions. The fish harvesting head is formed from a fish harvesting body having a barb receiving slot positioned in the forward portion of the fish harvesting body that extends along a longitudinal axis of the fish harvesting body. The barb receiving slot enables the barb to be quickly replaced or removed. The fish harvesting head may also include a piercing tip retaining device positioned in the barb receiving slot and in contact with an inner surface of the piercing tip for increasing resistance to movement of the piercing tip relative to the fish harvesting body and prevent accidental loosening of the tip. | 04-23-2009 |
20120102811 | System for Harvesting Marine Species Members Including Those that Present a Danger to a Harvester - Devices, methods, and systems are disclosed for harvesting a member of a marine species while minimizing or preventing contact between the harvester and the marine species. Certain embodiments reduce the opportunity for contact between the harvester and the harvested member by providing mechanical means for removing the harvested member from a spear. The invention method includes, in one case, the steps of impaling the marine species member, removing the member from the impaling device, and securing the removed member in a manner to prevent contact with the harvester during each step of the method. | 05-03-2012 |
20120246995 | RETRACTABLE KNIFE SPEAR - A retractable compact knife spear is provided. The knife spear may include a knife blade, as opposed to standard barbs and may be compacted to strap to a diver's leg. The retractable knife spear may include other features, such as sound signaling devices and may be used as a pointer when leading dive teams.

20130118052 | MULTI-PRONGED SPEAR-FISHING SPEAR TIP - 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. | 05-16-2013 |
