Releasing reversing spear is used for fishing, reversing and releasing the fish. It can catch and transmit left hand torque during reversing. It can replace left hand taper taps and die collars. The function is similar to reversing sub. The difference is that it doesn't need to make up thread with fish and catch at any part internally.
