  • Patent number: 5209685
    Abstract: An accessory serving as an aid for saving the life of an "ice" fisherman, snow mobile operator, or other recreation or sports minded person who ventures onto an ice covered lake, pond or other body of water and breaks through the ice. The accessory includes two ice picks connected together by a floatable cord. Each ice pick includes a casing forming a handle having elongated external recesses helpful for hand gripping, and a pair of notches or grooves to facilitate gripping by the thumb and index finger. Each casing has an internal bore configured to receive an ice pick, a spring biased sheath, and a molded floatation plug, enabling the accessory to float when dropped into a body of water. The floatation plug may be formed of a closed cell, foamed plastic. The floatation plug has circumferentially spaced slots which engage fins connecting a central pick holder to an inner surface of a bore within the handle.
