  • Patent number: 4947943
    Abstract: A fisherman's ice auger has a hollow tubular body with an open end and a closed end, and a support pivotably retaining a crank handle in either of a deployed position, for cranking the body about its axis, and a stowed position wherein the crank handle is pivoted back along the body for gripping and transporting the ice auger. Helical webs on an outside of the tubular body, extending helically away from the open end. Preferably-replaceable cutters are mounted at the ends of the helical webs. A removable cap overfits the open end of the body, closing off the inside of the tubular body and defining a receptacle for carrying ice fishing articles, and also protecting the cutters. The cutters have a disc-shaped or spade-shaped blade attached to the leading edge of a shoe mounted on the open end of the tubular body.
