SlipShaft™ (Patent Pending 61/328.182, 61/384.721) is a revolutionary spear design technology invented by Sean Lunasco in Hawaii (2010) primarily for the spear gun fishing industry. SlipShaft™ spears are so revolutionary because its body section in cases of a spear gun shaft or Pole Spear has the ability to slide well away from the break-away spear head along the leash (tether)/shooting line so the secured struggling prey has less of a chance to damage the spear shaft or Pole Spear. SlipShaft™ also improves the tension setup provided by the leash (tether)/shooting line to hold our uniquely designed break-away spear head on the shaft's front-end by using a revolutionary design. This revolutionary design allows routing of the leash (tether)/shooting line in an entirely different way than most are use to and ensures our uniquely designed break-away head seats snug and flush on the front-end so it will not separate unexpectedly or when it is not suppose to and significantly reduces wobble. SlipShaft™ technology also allows the shaft to not serve as an integral component of the overall leash (tether)/shooting line restraint system thus reducing points for failure.
SlipShaft™ has two primary models; Tube Shaft & Solid Steel Rod.
SlipShaft™ technology may also be utilized in similar applications (i.e. crossbow hunting, archery bow and arrow hunting, harpooning, drilling retrieval, mountain/tree/building climbing, rigging, electronic cabling or any other sport or application that involves the use of a spear and tag/keeper line).
